i have an idea for the code tab, add the option to change the color of the writing or highlight things, so that you can show people parts of the code easily
i think that a nice thing would be a thing that like every 2 hours says "check out the betas tab, check out the games and please feedback.
also, this would be really hard, but a way to actually put a game up, and people could go into the code and edit it for you, but you have to invite people to edit it, so its more private. if you could do that then this would be the best video game design chat EVER.
