Activation Groups

I've mentioned this before, but with new items being added to parts lists and more complicated rockets and spacecraft being built, it would be a good idea to increase the number of activation groups. I suggest 15 groups. I'm working on a shuttle that will need to utilize multiple activation groups. Example- Crew access arm retract, umbilical arm retract, Crew Hatch (cargo bay), cargo bay to launch a satellite, astronaut eject, astronaut parachute, antenna/device extension, drag chute deploy, drag chute release, RCS, landing gear, RCS OHMS (using enlarged RCS thrusters for fine orbit adjustment). I know that drag chute deploy and drag chute release can be staged items. If I release a satellite it will need activation groups to operate it. For complicated craft, 10 groups is not enough.
