bani, could you make it so with choosesmg, if you use one of the choosesmg commands, using that command twice in a row will put it back at the default gun? i.e. you use /thompson, no longer want the thompson and want the default gun, you could use /thompson again and the default would be restored.
I'm not saying doing that is too hard, all I'm saying is that typing the same command again to change back fits in more with the other banimod settings, like classes.
