When I using Goodnotes on the devices like Mac and iPhone where don't support Apple Pencil, here's something I wanted:
-- Letter beautification, the letters written by finger on whatever touchpad or screen is not tidy enough, this tool will make the ugly characters more beautiful, add even with font selection if possible
-- Graphics tool that draws shapes by dragging and dropping with a single finger
-- A more responsive text selection tool, and after selecting the text displays a toolbar similar to the one in Word, not the one that comes with Apple's system.
