Different users have unique needs from a note taking software which practically isn't possible to cover in a single app UI by developers. Therefore, two MODES, a MINIMAL/SIMPLE and an ADVANCED/PRO mode should be made. The simple mode should have about the same features as Goodnotes has right now and would be able to serve the general users. The advanced mode should let users customise their app UI as well as toolbars, tools, quick features, icons positions and ribbon placements and a lot of other features as per their need. This can be revolutionary as it'll cover all types of users, from generals to professionals.
