- Added support for Image - Added a QuickLook feature, to enable thumbnail generation. - Added support for NSButton. - Fixed a bug where App activation under Big Sur would leave menus without the ability to be used. - Added the ability for Buttons and ToolbarItems to execute callbacks. - Added support for Labels and TextFields. - Added support for MenuItems to have callbacks as well. - Preliminary ListView support; you have to cache your ListViewRow items yourself for the time being, but it works. - Animation support for ListView operations. - Support for ScrollViews. - Helpers for dispatching actions to the main thread (for UI work). - Updated the Dispatcher trait to make thread handling simpler. - Basic font support.
