Separate tool for drawing lines (and shapes)

^{Originally posted by **tuermana** September 10, 2023} There is an option in configuration named "hold to straighten a line" that is very useful but it often times screws up when coloring something. I think it would be better if it was another tool instead of a configuration so you can toggle it on or off and it will also allow to add more figures to draw like triangles, squares, etc. In that regard, a circle can be the first option to implement because you can draw almost any figure with just a line and a circle.

The current (v0.17.0) implementation makes it sometimes more difficult to draw straight lines when we take notes. I mean, previously, we can draw straight lines only via the stylet, but now, many steps are necessary.

I am not sure a better way to do this. The button on the stylet is already used to enable the eraser. An option is to click this button twice to enable the shape mode, which switches back automatically when the stylet leaves the touchscreen.
