-## Enum Combo Box
-
-`QEnumComboBox` is a variant of [`QComboBox`](https://doc.qt.io/qt-5/qcombobox.html)
-that populates the items in the combobox based on a python `Enum` class.  In addition to all
-the methods provided by `QComboBox`, this subclass adds the methods
-`enumClass`/`setEnumClass` to get/set the current `Enum` class represented by the combobox,
-and `currentEnum`/`setCurrentEnum` to get/set the current `Enum` member in the combobox.
-There is also a new signal `currentEnumChanged(enum)` analogous to `currentIndexChanged` and `currentTextChanged`.
-
-Method like `insertItem` and `addItem` are blocked and try of its usage will end with `RuntimeError`
-
-```python
-from enum import Enum
-
-from superqt import QEnumComboBox
-
-class SampleEnum(Enum):
-    first = 1
-    second = 2
-    third = 3
-
-# as usual:
-# you must create a QApplication before create a widget.
-
-combo = QEnumComboBox()
-combo.setEnumClass(SampleEnum)
-```
-
-other option is to use optional `enum_class` argument of constructor and change
-```python
-combo = QEnumComboBox()
-combo.setEnumClass(SampleEnum)
-```
-to
-```python
-combo = QEnumComboBox(enum_class=SampleEnum)
-```
-
-
-### Allow `None`
-`QEnumComboBox` allow using Optional type annotation:
-
-```python
-from enum import Enum
-
-from superqt import QEnumComboBox
-
-class SampleEnum(Enum):
-    first = 1
-    second = 2
-    third = 3
-
-# as usual:
-# you must create a QApplication before create a widget.
-
-combo = QEnumComboBox()
-combo.setEnumClass(SampleEnum, allow_none=True)
-```
-
-In this case there is added option `----` and `currentEnum` will return `None` for it.

+## Sliders not dragging properly on MacOS 12+
+
+??? details
+    On MacOS Monterey, with Qt5, there is a bug that causes all sliders
+    (including native Qt sliders) to not respond properly to drag events.  See:
+
+    - [https://bugreports.qt.io/browse/QTBUG-98093](https://bugreports.qt.io/browse/QTBUG-98093)
+    - [https://github.com/pyapp-kit/superqt/issues/74](https://github.com/pyapp-kit/superqt/issues/74)
+
+    Superqt includes a workaround for this issue, but it is not perfect, and it requires using a custom stylesheet (which may interfere with your own styles).  Note that you
+    may not see this issue if you're already using custom stylesheets.
+
+    To opt in to the workaround, do any of the following:
+
+    - set the environment variable `USE_MAC_SLIDER_PATCH=1` before importing superqt
+    (note: this is safe to use even if you're targeting more than just MacOS 12, it will only be applied when needed)
+    - call the `applyMacStylePatch()` method on any of the superqt slider subclasses (note, this will override your slider styles)
+    - apply the stylesheet manually:
+
+    ```python
+    from superqt.sliders import MONTEREY_SLIDER_STYLES_FIX
+
+    slider.setStyleSheet(MONTEREY_SLIDER_STYLES_FIX)
+    ```

-- `QRangeSlider` inherits from [`QSlider`](https://doc.qt.io/qt-5/qslider.html)
-  and attempts to match the Qt API as closely as possible
-- Uses platform-specific styles (for handle, groove, & ticks) but also supports
-  QSS style sheets.
-- Supports mouse wheel and keypress (soon) events
-- Supports more than 2 handles (e.g. `slider.setValue([0, 10, 60, 80])`)

-## Range Slider
-
-```python
-from superqt import QRangeSlider
-
-# as usual:
-# you must create a QApplication before create a widget.
-range_slider = QRangeSlider()
-```
-
-As `QRangeSlider` inherits from `QtWidgets.QSlider`, you can use all of the
-same methods available in the [QSlider API](https://doc.qt.io/qt-5/qslider.html).  The major difference is that `value` and `sliderPosition` are reimplemented as `tuples` of `int` (where the length of the tuple is equal to the number of handles in the slider.)
-
-### `value: Tuple[int, ...]`
-
-This property holds the current value of all handles in the slider.
-
-The slider forces all values to be within the legal range:
-`minimum <= value <= maximum`.
-
-Changing the value also changes the sliderPosition.
-
-##### Access Functions:
-
-```python
-range_slider.value() -> Tuple[int, ...]
-```
-
-```python
-range_slider.setValue(val: Sequence[int]) -> None
-```
-
-##### Notifier Signal:
-
-```python
-valueChanged(Tuple[int, ...])
-```
-
-### `sliderPosition: Tuple[int, ...]`
-
-This property holds the current slider positions.  It is a `tuple` with length equal to the number of handles.
-
-If [tracking](https://doc.qt.io/qt-5/qabstractslider.html#tracking-prop) is enabled (the default), this is identical to [`value`](#value--tupleint-).
-
-##### Access Functions:
-
-```python
-range_slider.sliderPosition() -> Tuple[int, ...]
-```
-
-```python
-range_slider.setSliderPosition(val: Sequence[int]) -> None
-```
-
-##### Notifier Signal:
-
-```python
-sliderMoved(Tuple[int, ...])
-```
-
-### Additional properties
-
-These options are in addition to the Qt QSlider API, and control the behavior of the bar between handles.
-
-| getter               | setter                                      | type   | default | description                                                                                      |
-| -------------------- | ------------------------------------------- | ------ | ------- | ------------------------------------------------------------------------------------------------ |
-| `barIsVisible`       | `setBarIsVisible` <br>`hideBar` / `showBar` | `bool` | `True`  | <small>Whether the bar between handles is visible.</small>                                       |
-| `barMovesAllHandles` | `setBarMovesAllHandles`                     | `bool` | `True`  | <small>Whether clicking on the bar moves all handles or just the nearest</small>                 |
-| `barIsRigid`         | `setBarIsRigid`                             | `bool` | `True`  | <small>Whether bar length is constant or "elastic" when dragging the bar beyond min/max.</small> |
-------
-
-### Examples
-
-These screenshots show `QRangeSlider` (multiple handles) next to the native `QSlider`
-(single handle). With no styles applied, `QRangeSlider` will match the native OS
-style of `QSlider` – with or without tick marks.  When styles have been applied
-using [Qt Style Sheets](https://doc.qt.io/qt-5/stylesheet-reference.html), then
-`QRangeSlider` will inherit any styles applied to `QSlider` (since it inherits
-from QSlider).  If you'd like to style `QRangeSlider` differently than `QSlider`,
-then you can also target it directly in your style sheet.  The one "special"
-property for QRangeSlider is `qproperty-barColor`, which sets the color of the
-bar between the handles.

-
-![labeled_range](images/labeled_range.png)
-

-
-This has the same API as `QRangeSlider` with the following additional options:
-
-#### `handleLabelPosition`/`setHandleLabelPosition`
-
-Where/whether labels are shown adjacent to slider handles.
-
-**type:** `QLabeledRangeSlider.LabelPosition`
-
-**default:** `LabelPosition.LabelsAbove`
-
-*options:*
-
-- `LabelPosition.NoLabel` (no labels shown adjacent to handles)
-- `LabelPosition.LabelsAbove`
-- `LabelPosition.LabelsBelow`
-- `LabelPosition.LabelsRight` (alias for `LabelPosition.LabelsAbove`)
-- `LabelPosition.LabelsLeft` (alias for `LabelPosition.LabelsBelow`)
-
-#### `edgeLabelMode`/`setEdgeLabelMode`
-
-**type:** `QLabeledRangeSlider.EdgeLabelMode`
-
-**default:** `EdgeLabelMode.LabelIsRange`
-
-*options:*
-
-- `EdgeLabelMode.NoLabel`: no labels shown at slider extremes
-- `EdgeLabelMode.LabelIsRange`: edge labels shown the min/max values
-- `EdgeLabelMode.LabelIsValue`: edge labels shown the slider range
-
-#### fine tuning position of labels:
-
-If you find that you need to fine tune the position of the handle labels:
-
-- `QLabeledRangeSlider.label_shift_x`: adjust horizontal label position
-- `QLabeledRangeSlider.label_shift_y`: adjust vertical label position
-
-### `QLabeledSlider`
-
-![labeled_range](images/labeled_qslider.png)

+The `superqt.fonticon` module provides a set of utilities for working with font
+icons such as [Font Awesome](https://fontawesome.com/) or [Material Design
+Icons](https://materialdesignicons.com/).
+
+## Basic Example
+
+```python
+from fonticon_fa5 import FA5S
+
+from qtpy.QtCore import QSize
+from qtpy.QtWidgets import QApplication, QPushButton
+
+from superqt.fonticon import icon, pulse

+app = QApplication([])
+
+btn2 = QPushButton()
+btn2.setIcon(icon(FA5S.smile, color="blue"))

+btn2.show()
+
+app.exec()
+```
+
+{{ show_widget(225) }}
+
+## Font Icon plugins
+
+Ready-made fonticon packs are available as plugins.
+
+A great way to search across most available icons libraries from a single
+search interface is to use glyphsearch: <https://glyphsearch.com/>
+
+If a font library you'd like to use is unavailable as a superqt plugin,
+please [open a feature request](https://github.com/pyapp-kit/superqt/issues/new/choose)

+# QIconifyIcon
+
+[Iconify](https://iconify.design/) is an icon library that includes 150,000+
+icons from most major icon sets including Bootstrap, FontAwesome, Material
+Design, and many more; each available as individual SVGs.  Unlike the
+[`superqt.fonticon` module](./fonticon.md), `superqt.QIconifyIcon` does not require any additional
+dependencies or font files to be installed.  Icons are downloaded (and cached)
+on-demand from the Iconify API, using [pyconify](https://github.com/pyapp-kit/pyconify)
+
+Search availble icons at <https://icon-sets.iconify.design>
+Once you find one you like, use the key in the format `"prefix:name"` to create an
+icon:  `QIconifyIcon("bi:bell")`.
+
+## Basic Example
+
+```python
+from qtpy.QtCore import QSize
+from qtpy.QtWidgets import QApplication, QPushButton
+
+from superqt import QIconifyIcon
+
+app = QApplication([])
+
+btn = QPushButton()
+btn.setIcon(QIconifyIcon("fluent-emoji-flat:alarm-clock"))
+btn.setIconSize(QSize(60, 60))
+btn.show()

 `superqt` provides two decorators that help to ensure that given function is
 running in the desired thread:
 
-* `ensure_main_thread` - ensures that the decorated function/method runs in the main thread
-* `ensure_object_thread` - ensures that a decorated bound method of a `QObject` runs in the
-  thread in which the instance lives ([qt

 an instance of
 [`concurrent.futures.Future`](https://docs.python.org/3/library/concurrent.futures.html#concurrent.futures.Future)).

+the combobox based on a python `Enum` class.  In addition to all the methods
+provided by `QComboBox`, this subclass adds the methods
+`enumClass`/`setEnumClass` to get/set the current `Enum` class represented by
+the combobox, and `currentEnum`/`setCurrentEnum` to get/set the current `Enum`
+member in the combobox. There is also a new signal `currentEnumChanged(enum)`
+analogous to `currentIndexChanged` and `currentTextChanged`.
+
+Method like `insertItem` and `addItem` are blocked and try of its usage will end
+with `RuntimeError`
+
+```python
+from enum import Enum

+from qtpy.QtWidgets import QApplication

+- `QRangeSlider` inherits from [`QSlider`](https://doc.qt.io/qt-6/qslider.html)
+  and attempts to match the Qt API as closely as possible
+- It uses platform-specific styles (for handle, groove, & ticks) but also supports
+  QSS style sheets.
+- Supports mouse wheel events
+- Supports more than 2 handles (e.g. `slider.setValue([0, 10, 60, 80])`)
+
+As `QRangeSlider` inherits from
+[`QtWidgets.QSlider`](https://doc.qt.io/qt-6/qslider.html), you can use all of
+the same methods available in the [QSlider
+API](https://doc.qt.io/qt-6/qslider.html). The major difference is that `value()`
+and `sliderPosition()` are reimplemented as `tuples` of `int` (where the length of
+the tuple is equal to the number of handles in the slider.)
+
+These options are in addition to the Qt QSlider API, and control the behavior of the bar between handles.
