I would also really like this!
For me, I will have games and comics and I really want to make them obviously separate... but for other people maybe it's games and software or different types of games.
I'd just like to be able to have the games displayed under different headers. I think it would make other people's profiles easier to look at, too. Some people have a lot of different projects... Often I want to be able to see at a glance which ones are playable in the browser, instead of having to click on every game page. When we upload our games we give them their own noun (custom or "game" or "comic" or whatever), so maybe it would be possible to group them on a page with that.
