Having, for example, a carrier that docks 20 AI fighters would be really hard to launch them while having only 9 slots in the quickbar, for this and many other uses I suggest the follwoing:
Relay computer that acts like any other computer but you can connect other modules or computers to it so that you can trigger all of them in a single quickbar slot, for example the relay computers connects to all docking modules and asigning the relay to a key and clicking would undock all the ships.
Bigger quickbar by having it either scrollable using some key combination or just having an additional quickbar that you can click on by using F2 to deatach mouse or something.
