what is neo-quicksettings-for-koreader fr?

Neo QuickSettings is a plugin for KOReader, the open source e-reader software used on devices like e-ink tablets, that replaces the standard quick settings panel with a much more customizable one. Instead of digging through menus, a reader can pull up a single panel to adjust brightness, warmth, and shortcuts, with far more control over how everything looks and behaves than the built in options allow. One of its main features is a visual icon picker, so instead of typing or guessing icon names, a user can browse through hundreds of icons across different styles and pick one just by looking at it. The plugin also lets people build their own custom buttons tied to specific actions or scripts, with a draft and discard system that lets changes be tested safely before they are made permanent. Frequently used actions can be grouped into favorite tabs to keep the panel tidy, and up to four sliders can be set up for controlling frontlight brightness and warmth, either as smooth sliders or in fixed steps. Beyond that, the plugin supports deep visual customization: buttons can be shown or hidden, labels changed, icon sizes adjusted, borders toggled, and the whole layout arranged however the user prefers. It also integrates with something called SimpleUI, letting favorite shortcuts be sent directly to that launcher. To install it, a user downloads the plugin, copies its folder into KOReader's plugins directory, and separately copies an included icon file into KOReader's own icons folder, then restarts the app. After that, the panel can be opened from KOReader's menu or triggered with a gesture, and further customized through a settings menu reached by long pressing a button or tapping the gear icon. The project builds on earlier work from other KOReader community developers, crediting the creators of an existing quicksettings plugin, an earlier UI system called Zenui, and the original patch that started the idea, and it is released as open source itself.
