This may have been (probably has been) suggested before, but I would really like the ability to sort planets by faction. The current system of hunting through the system map or scrolling through the entire list of markets is tedious. Being able to quickly see a list of all markets of a faction would greatly expedite trying to hunt down missions and the like.
Unless of course this function already exists and I just don't know how, in which case: How do you sort the planet list by function?
