KDDockWidgets is by now a very mature product.
Future development will be focused on finishing the Flutter frontend and improving Wayland support.
QtQuick API will also mature, as users give feedback.
There's nothing planned for QtWidgets, but feature requests and bug reports will be honoured for the foreseeable future.

Features and bugfixes for maybe 2.x or 3.0

  • QtQuick: Improve API
  • QtQuick: API for specify min/max sizes
  • QtWidgets: Make TitleBar more configurable, so user can inherit from it and customize more
  • Core: Cleanups for button handling, normalize code for all button types.
