Hi, Michael,
Tried out the new patch and it works fine, especially the persistent construction lines, once I figured out how to activate the persistent behavior. One quirk I noticed though, is that in the middle of a command,
pressing a single letter key to activate a script doesn't work, because the keystroke gets intercepted and sent to the coordinate box at the bottom (which is what it's designed to do ), Modifier+key works fine. Maybe a filter on the input boxes to reject any kind of keystrokes other than numerals would work better?
I noticed this awhile ago, doing something else, but since it wasn't affecting what I was doing, it kind of slipped on by.
At any rate, thanks for the construction line work, it works well having them stay on screen :)
