PistonFilter
Now you can set which blocks the piston will (don't) move.



The idea is inspired by this resource.

All you have to do to specify the filter is place a frame on the piston and put in a frame any block. A framed block rotated 45 degrees means "not".

Carefully! The plugin may be causing lag with more pistons!
