In Stringer one of the best commands in here is the Point Group Commands.
It will alow you to Rotate Move or Scale point groups without having to turn off all other point groups to edit a days work that has an issue associated with it.
I like these commands because Stringer is the only one where you can rotate things just by selecting the point group you want and giving it a rotation or a move by selecting on the screen.
Also when doing a scale with the normal AutoCAD command, it can scale the Z values which is not required, where in Point Group Commands we can select a group and only scale it in the 2D Plane only (X,Y) .
Very handy for multiple day jobs with any errors that need fixing by a Point Group
