Default undo's to unlimited
Instead of hiding history tabs and amounts of undo's in hidden history settings buttons that are difficult to find for most people just increase undo amount... no one I know uses history they just click undo and redo...
Very different to photoshop

If unlimited takes too much RAM at least make it 100 as the default instead of 32...
For those wondering where the history settings button is. Window -> history -> (3 horizontal lines) menu button -> settings
