Spring RTS Engine

This widget enable you to switch cameras quickly between your comm and you start position. It switches to whichever is more distant.
Currently its bound to ctrl+shift. You can also change it in the widget code to be alt+shilt or even just shift. If its only shift, then the widget will also activate while typing into the console, so I dont recommend that.

You can also just bind it to any key using:
bind [key] luaui fastswitch

For example edit your uikeys.txt to bind it to tab:

unbind any+tab toggleoverview
bind any+tab luaui fastswitch

Updated to not crash if pressed before game starts, and to use TraceScreenRay to get the ground coordinates of your current camera position.
