Hi Max,

Another amazing script, thanks! Very useful indeed!

I really like christian's suggestion above, especially if the rectangle would snap to specific distances, so you can neatly place all annotations at the same distance from your drawing.

Ideally, we'd be able to set the offset from the text relative to the line, as well as the offset of the 'overshoot' of helper lines - usually you'd have this, instead of placement at very the end of these lines.

Thanks again, kind regards,

Fabien
