hmm a control block sounds very nice but i think it is more preffered in the following way:
why not add a \'\'control block\'\' that has a bounding box like a turret docking unit, which can be expanded likewise with different compatible enhancers, which activates linked blocks like plexdoors, gravity units, dis-integrators or any other block that can be activated that has no inventory/gui screen upon activation like the plexstorage, or a computer parent like amc\'s have.
this makes for auto adjusting gravity rooms, auto plexdoors, or anti personel mines for example.
