Please look into the possibility to have officers remove players. The faction leader is the only member that has this function. Make it so the leader can give this ability to certain officers.

Please develop a system that if the leader should leave a faction, an officer can step up and assume control of that faction.

I also like the ally search idea. I would visit specific ones more if I didn't have to scroll through so many pages.

It would be nice to be able to see what a building would cost to upgrade even though another building is currently upgrading. Helps with budget planning for upgrades.

Last is have a confirm button on your vault upgrade. A few weeks ago I accidentally upgraded my vault and it cost me 700 gold. I submitted a ticket and you promptly returned my gold. Thank you for that service too! I am grateful.
