The current ruler is fine when drawing, but when it comes to taking note, using the rule is SO INCONVENIENT!! The "Draw and hold to create straight line and other shapes" is definitely needed!!!
P.S. The "draw and hold to create perfect shape" feature in Goodnotes and Notability is perfect, but the writing experience in Flow is just irreplaceable, I don't want to switch back to other apps!!! Please add this feature soon😢😢😭😭
