Maybe you can just condense all your wishes in one post, rather than make a few dozen posts for each individual item?

cybernetic implants with hard points
or, shall we call them 'cyber points'
basically, if you want to make a cybernetic enhancement with a cybernetic cavity, it counts as 2 separate cyber upgrades. if you get your arm hacked off in a saber fight and you want to be able to smuggle your lightsaber in your new arm, it makes sense to build a cavity in to the arm. this could easily be done by not getting the current boost to upgrade brawn or agility.
or, if you are a slicer, having lock picking tools or other upgrades built in to your limbs would be beneficial.

i add this discussion because i have a gm who only allows things listed in the books, and it gets tiresome arguing it when it could just be made that way...

this is a 'correct me if i'm wrong' post, but i've been reading special modifications. if i read it correctly, what i said can be done. i get the template with the gear i want to add, then pass the appropriate skill checks and, whammo, arm with cybernetic cavity
