Straight line drawing tool for RV annotation

I am wondering if we have a plan to add straight line drawing tool for RV annotations.
or is it even possible to tweak the draw tool?

It is really difficult to draw straight line with current tool.
I wish we had the same tool from MS paint at least.
It would be the best to have the bezier tool.

The built-in UI does not contain a mode for straight-line. But the RVPaint node itself supports it.

If you put 2 arbitrary points in its pen:id:frame:user.points property, it will effectively render a straight line between those 2 points.

This can be done through scripting or by tweaking the UI code to add your custom straight-mode to it.
