Word filters: If an individual doesn't like words being said then they can set up their own word filters to block words they may find offensive. A Default script can be created during install and switched on in the controls.
Favorites/Blacklists: Some servers are run well and you have a good time on; others are run by the spawn of satan and deserve not to get traffic. Therefor, when your server list is refreshed your favorite servers appear at the top, and blacklisted servers at the bottom. To favorite or blacklist a server you simply click in an icon in a box next to it to change it from a thumbs up or thumbs down or thumbs sideways symbols (or something equally as simple). Additionally, when a server bans you, the listing status shouldn't be changed but the server gets a B in the spot.
Regions: Basically, there should be 6 regions when a server is listed: North America East, North America Central, North America West, North America Canada, Europe, Asia, and Other. When a server lists itself, it lists itself in one, or more, categories. When a client makes a request to the master server, it asks for 1 or more of these lists. This reduces unwanted bandwidth use by the server and keeps 500-server long lists down to 50-100 good servers.
Pub and Tournament modes: Pub mode is used for pubbing; players freely join teams and can switch to another team or to obs freely and may set their settings based on what they want and may use whatever scrips and gui's they choose. In Tournament mode, players join a game and are subject to automatic team placement or placement by the admin, having their settings changed upon joining the server, passworded and other useful features such as an obs recorder or auto-force-recorder at game start, for example.
Automatic Auto-team select: Server admins can force players to join a team at the game start, within the first minute or two of gameplay and players who were left over from the previous game may not switch teams or to obs without waiting 5 minutes. This stops the problem of teamstacking mulitple games in a row.
