I was going to post a new thread but I just decided to put it in here.
For RC:
1) In the playerlist menu, make it possible to edit the players name (if needed, make it a right that you are able to edit players names) as in if you click their name, it highlights it than makes a text box for you to put in a new name (or edit it).
2) Ignore, yes RC is to do your job but sometimes there are people who just like to annoy you constantly (like it is their hobby) and so the ignore option would be useful (if you don't like it you don't have to use it). (This was probably mentioned in other threads)
3) Have different themes (skins) for RC, green gets boring really fast
(This was probably mentioned in another thread too).
4) More server options, maybe a
normaladminscannotdisconnectnpcserver=true
so that even if an RC accidentally clicks disconnect on npc-server, it would not disconnect because it is not possible. Any other ideas, list them here.
