This has most likely been suggested before, but I would like to bring this to attention once again. I think that it would be a wonderful idea to have more factions ranks than just leader, officer, and member. At the very least more default ranks can be added to the plugin to provide more diversity and status within a faction. An even better idea would be to give full control to the faction and allow the ability to create custom ranks, and adjusting every possible permission for each rank (so for instance you can have a leader, and a co-leader with identical permissions).
