It is the oh so magnificent Orbital Eunuchs Sniper TODO list, ordered in order of orderly importance!
New features should:
Always be toggleable in the GUI, and from the cli, if there ever become enough of them, then we should have a toggle for 'Classic' mode.
There may or may not be more interesting ideas at https://bugzilla.icculus.org/

1.3 Implementing the new recharge sound Emmett made
1.3 CLI options to disable music OR sound fx
1.3 ASCII art on exit, just like the old id games!  
1.3 Windows build

1.4 New Levels
1.4 Level selection in the menus
1.4 Level editor gimp plugin
1.4 Levels

1.5 Get some kind of tremor in this here shiznit.
1.5 Port to Zaurus/opie/whatever.
1.5 Resolution switching (it's required for the above)

1.5.1 (I'm guessing it's due to the vorbis decoding, actually)
1.5 Somebody make a freaking icon already.
