Hmm, someone not knowing how to host up coop brought me up something useful...

How about expanding the server startup options? Allow backtyping and put the plus gamemodes in the starting gamemodes, which would probably mean smaller text to make sure things to fit into the screen too. Also making a servername should allow the oppurtunity to give/preview colour, like with user screen names. Also, battle maps in the maplist should be compatible with roast tag, team battle, lrs, xlrs and tlrs, instead of having to add them individually for each gamemode in the ini, also so that people don't have to keep switching back to battle mode just to make the cycling work for non-hosts.

Also, plus should have that if you try to cycle to a level in your cache where you don't have the tileset in your folder, if would come up with something like "Error: (tilesetfile).j2t not found!" in red console text, instead of crashing the game completely forcing you to restart.

Also, having the option to put an actual music file instead of boss music ID for activating bosses would be really awesome and far more convenient.
