In the latest StudioPro we introduced a global level undo / redo feature which applies to all UI elements including scenes, schedulers, timelines and more.
The undo / redo is a global feature so it will allow for navigating between different window panes while undoing and redoing your latest changes.
The feature also has an unlimited memory stack so you can go all the way back to your initial changes since your last save/sync.
You can also use Cont-z / Cont-y for the global level undo / redo.
Enjoy!
