At present, the server filter dialogue has a "MISSION:" text box, allowing you to show only servers with a specified string in their mission names. It would be useful to be able to find servers with missions that do *not* contain a specified string as well, either with a second text field, or with simple Google-style syntax like "-Wasteland".

- Menu UI
This isn't intended as another "stop people making Wasteland servers" non-bug. It is inevitable that certain mods and missions will sometimes become sufficiently popular that they make the in-game server browser less usable for people who want to play other missions, and I am sure that as Arma 3 gains popularity, it will happen again with something other than DayZ and Wasteland.
Allowing negative server filters would make server browsing much easier and faster for these players.
