I know it isn't easy in the slightest to add things to admin tools, but I thought I may as well compile a wishlist of what I would love to have available :3
1) Spectate tool - list of all players, click on the name of one, it moves your camera to them in spectate mode. This would be so useful on servers involving large numbers of people, for example battle servers and especially siege servers.
2) Some sort of report tool - a way in which players can talk to admins directly, for example like the system used in PW
These are just some ideas I had, feel free to comment on them or add your own ideas. As I said, I know it wouldn't necessarily be easy to add, but it would make things a lot easier
