When you need to draw a perfect line, rectangle, circle etc.
If you draw a rough box or circle or other shapes it can recognise this and adjust the shape so it’s an actual box or circle
Agreed. A Shape Tool like most illustration software has. Also a line tool and a ruler.
In other apps this is often realized when holding the pen stroke after finishing the line/box/circle. Like this the app „knows“ when it should convert the drawing to a perfect shape and when it shouldn‘t.
This would be extremely helpful
YES. Super useful!
Yes, and please also add the ability to draw arrows as well. The tool is called "flow" after all and arrows are key to any good flow chart/diagram.
