Wow, I tried it out, and it was better than I expected to be. I do have a couple suggestions though, I don't know how hard this would be, but would it be possible to code it so it ignore's certain groups? say if I wanted to make my own group called: cool guys, but they don't inherit from admin, so they're not immune to anti-AFK. But if I went into the lua folder, and changed a few things, such as: groups this affects, and say "cool guys" when I would save it, it will no longer affect that group.
My second suggestion is; you could put something in where it does ignore admins, and after a set of time it will give them the tag of AFK, but the auto-kick will ignore them. Say if there's a server full, and I need to kick an AFK for a friend/server owner. there could be an AFK admin/moderator, but since they're immune to anti-AFK I can't tell if he's AFK or not. if you were to do the above, then we could easily tell if ANYONE on the server is AFK, and if we really needed to, we would kick an admin/moderator for someone else.
That's all I have for now. If I have any other suggestions, I'll post them here.
Thanks for reading.
