Actually...you CAN choose your colours in single player, and I'm working on a program to do it (I'll post it on J2O as soon as it is finished).



And about 1.25...hmmm

• Have memory addresses for cheating change every game, but keep non-cheating ones the same (otherwise great programs like CoolText and ChatLogJJ2 wouldn't work)
  
• Finish all the events in JCS
  
• Simple macros for levels (where you can put in IF statements and things, like "if (player.number == 1) { Level.Tile[24][12] = TILE_BLANK_TILE; } else { Level.Tile[24][12] = Level.Tileset.Tile[2]; }" I don't know if that would be the way macros work, but what I just wrote would make a blank tile for the server, but I real tile for everyone else. This could be useful, but not limited to, hotels and employee rooms (for those who still use them).) Maybe also some things to automatically add you to the hall of fame if you beat the test level, and other things such as that.
  
• Voice Chat (for people with microphones)
  
• and much more...
