Hi,

While using the sketch tool, maybe the automatic dragging of object could be temporarily disabled?
I often drag objects unintentionally while trying to draw a line near another one.

Also having the right click temporarily disabled while using sketch would be nice.
When using a tablet, accidentally hitting the right click in the middle of a mile long path can be a bit frustrating.

I use Moi's sketch tool surprisingly often to trace stuff, I like it more than other vector tools, it usually generates better curves and b'splines are more fun than bezier for tweaking shapes in my opinion.
