- shortcuts: add a shortcut api, e.g. parse "&Save" and/or "Save (CTRL+S)", pass in to widgets or provide simple ways to use (button=activate, input=focus)
!- keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing
- keyboard: full keyboard navigation and focus. (#323)
- focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
- focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
- input: rework IO system to be able to pass actual ordered/timestamped events.
- input: allow to decide and pass explicit double-clicks (e.g. for windows by the CS_DBLCLKS style).
