I think it'd be neat if I could switch on some option (or buy some item) to guide me through the missions and flashpoints in as close to canonical order as possible. I know a lot of people enjoy the exploration aspect of finding quests and doing things as they occur, but making sure I do everything (especially exploration missions) kinda drives me nuts, even though it's optional. Instead it'd be awesome to just get a list of the next thing I should do, so whatever planet or flashpoint that's earliest in the story that I haven't done yet, that pops up in my tracker, I travel there, do it, and the next thing pops up.
