Could you (or someone) make this work with cars? I want to copy the filters of one car to a bunch of other cars, but this does not work with cars...

I was confused at first why it wouldn't currently work with cars, but it's actually quite simple:
The selection tool was only selecting entities a blueprint would select, and cars are like the only thing that are not blueprintable.
I've changed it to select literally any entity, which includes rocks, trees and tile-ghosts sadly, however to keep the mod as simple and as compatible as possible it'll just have to be like that. It doesn't affect behavior anyway, it just slows the mod down if they happen to be selected.

Anyway, update will be comming very soon, thanks for letting me know :)

All done, it's also cleaned up now, for a proper 1.0.0 release... with some programmer art :P
