Feature suggestion: lock the guideline angle

It would be nice if it is possible to lock the guideline angle. In that case, an angled guideline could be used to measure strokes angles without being messed up mistakenly.

You can lock the guide. Do you need to move the guide?

Yes, I need to move it everywhere to measure different stroke angles in different glyphs. So just lock the angle of the guideline will be great help to prevent mistakes.

I see. I put it on the list.

Thank you very much.
