Pardon me if this has been dealt with before, but phraseological differences prove searching a challenge, sometimes.
How can I turn “snapping” off in Engrave mode? Sometimes you need just that little more room for a frame, and then it “snaps” to the border; whether top, bottom, left or right.
You’re right.
You can also do fine adjustments from the properties panel. I think it has been announced that you’ll be able to edit frame handles from the keyboard in the upcoming update.
