Please bring the Grasshopper kill switch back!

I run in cases where the canvas can only be zoomed, and no more selection can be made.
The only way to get out of this is to kill Rhino+GH and open the whole thing again.

In the olde days, I would just kill GH with a hardy “GrasshopperUnloadPlugin”, run it anew, and it would be juuuust fine.
