I think that Discovery Freelancer Mod already has enough factions and systems and bases.
I think that the next mod should contain mostly upgrades.
Examples:
A lot of bases still have the wrong background image and wrong bartender.
A fix in the rep system.
A battleship,destroyer,gunboat,cockpit fix.There is a topic on this.
I personally would like a rogue battleship and custom equiptment.
Some systems are still pretty empty.
