Shot limits: Why does it send a server message for shot limits? Why can't it just display how many shots you have left? Like, it could display how many shots you have below the flag name in the top right corner. This would be useful, because you'd know how many shots you have before you fire once, and if you forget how many shots you have left, you don't have to scroll up and check.
Permanent flags: In the options section of a map, it would be cool if you could give all the tanks the effect of a certain flag. So if it was a wings battle map, you could put -wg in the option, and everyone would be able to fly without a wings flag. And they could also have other flags but still be able to fly. Sort of like -j and +r, except for all the flags, not just jumping and ricochet.
Zones: Have more options for the zone object. Like everything in "options" could be in a zone too? So if you had an elevator, you could just make a zone and set gravity really low in that zone.
Physics: Would it be possible to set it so you can have physics on the sides and bottoms of objects?
Teleporters: How come you can't use spin on teleporters? It would be useful to have some teleporters that are flat and you can jump/fall through them.
