PLEASEEEEEEEE make the 'Two finger tap, Three finger tap' undo/redo an option for users, I am constantly undoing/redoing things on accident just by writing. It is SO FRUSTRATING because I have been using the actual 'undo' button in the toolbar for years and am so used to reaching for it. all of the recent updates are GREAT, except that you don't have the option to 'opt-out' for certain changes.
