could you do this same thing with the Matter mover?

Is there any possibility of adding a version of this mod that only works in increments of 45 or 22.5 degrees, i.e. only -45, 0, and +45 degrees.

Dealing with 1-degree precision would be a bit too much hassle for me given how many button presses you'd need to get it into the proper position.
Additionally, knowing myself, would get messy really fast.

Because of this, I'm hesitant to use it in the current state, despite really liking the idea as well as the stuff about source and target percentage limits.

I could of course solve the second issue by simply make sure always change it by 45 degrees any time I use it, but that still requires op to 45 button presses for each targeted LET, which would be quite frustrating.
