When you need to draw a perfect rectangle, circle etc.
Even just straight lines to begin with
Shapes and a ruler would be very useful!
I would suggest you guys take a look at NoteAlways implementation of this feature. It’s very natural. You don’t have to preselect any tool, just draw something that looks like a circle/line/rectangle and a small icon appears next to the drawing. Click it and the drawing gets reshaped to be more circular/straight/square. Even better, the new shape is not perfect, still resembles something handdrawn, which I find very elegant (as opposed to some perfect shapes amid your handdrawn shapes).
very limited at the moment. maybe add a shape tool, rulers,.. more note editing features
Hi Olu, if you don't mind I'm going to merge this post into a similar one and create a new one for your suggestion of rulers. Thanks!
