Please post here scripts that can be described as one-click commands.
I hope these commands will be useful, mostly (but not only) while working in XYplane.
For example I'll post first one: 'Rotate90degrees'.
It is made by fixo and posted here as RS:

I made slight modification to eliminate manual entering the rotation value.
It needs little tuning to work correctly with undo/redo but I don't know how and what to modify.Now I'll ask again fixo to modify above and post here MIRROR-X(about X axis) and MIRROR-Y(about Y axis) using same start point (middle of selection set).
