Controlling (or Any) Faction State - Avoid opening the system map repeatedly to inspect each system.

Trading Networks - (Black) Market Network.
https://forums.frontier.co.uk/showthread.php?t=106723 - Black Markets.
https://forums.frontier.co.uk/showthread.php?t=99214 - Black Market Network.
Next, a few other suggestions.
https://forums.frontier.co.uk/showthread.php?t=103254 - Combinations such as Allegiance/Economy.
https://forums.frontier.co.uk/showthread.php?t=102125 - Minor Faction Reputation.
https://forums.frontier.co.uk/showthread.php?t=99214 - Outstanding Bounties/Fines, Reputation, Credits Earned.
Finally, a few suggestions of my own that I haven't seen elsewhere.
System Age - Just because.
Trading - Tons of commodities bought and sold, or trading profit.
Combat - Bounties and Combat Bonds claimed, or ships destroyed.
Mining - Quantity of system reserves, only known/explored systems.
Mining - Belt and ring types, only known/explored systems.
I intended a quick post with a few suggestions of my own, but started reading deeper into the forum and found a large number of similar suggestions and requests. Since there is a lot of overlap between the various suggestions, I decided to summarize and link them all. There seems to be a high demand for additional Galaxy Map filters in the community, especially when it comes to exploring and locating both players and conflict zones.
