• Format mnemonics
• Figure out how to detect when decoration->windowId changes so I can update AppMenuModel->winId as KWin reuses the decorations I think. It will sometimes show the menu for Dolphin over top a SublimeText window.
• Refactor to use QMenuBar or implement:
  • Switch submenu on Hover.
    • DecoratedButton::hoverEnterEvent
  • Switch submenu on Left/Right Arrow.

  • Open Submenu on Shortcut.
    • SublimeText has mnemonics, and opens app submenus at the top left of the window (relative (0,0)). So I'll probably need to adjust the position during an aboutToOpen signal or something. Or update it's position during updateButtonGeometry.
    • The shortcut opens the LIM submenu instead of the Global Menu in Sublime Text, which is a good sign.
    • Decorations don't recieve KeyEvents afaik. So it's not possible to detect Alt pressed. I don't think it's possible to detect a menu shortcut either. Gtk menus open (in the wrong spot), but Qt menus don't at all.

  • Display mnemonics when holding Alt.
  • Create an overflow menu when there isn't enough room for all menu items (Issue [Bug] Menu overflow #10)
  • Open menu on press instead of click.
• Filter empty menu items without a label (Gtk apps 1st item).
• Re-enable drawing the caption, using a gradient when covered by the appmenu.
• Fix all menu items disabled
  • 
  • SublimeText > Preferences > Theme > Press Esc to close
  • This probably rebuilds the menu. The QActions inside the KDecoration buttons were probably deleted?
• Window does not get focused when menu is clicked (Issue Window does not get focus back when clicking on app menu buttons #3)
  • Note this affect the AppIcon and default AppMenu buttons too.
• Fix invisible hitbox over the first menu item that triggers the menu overflow button.

Features

• Hide menu on model windows.
