Probably not something that needs to be high on the priority list (I'm not desperate for it, just something I think would be nice) but specifically I'm thinking:
Several categories for "games" and other things, so rather than having a block of all my things together I'd have a block of finished games, a block of work-in-progress things, a block of development tools and assets. That kind of thing.
I think maybe it could be accomplished by letting people disable all their game links, and add links into their profile in a layout they want via the user settings page - but right now those links don't show thumbnails the same as the rest of the site, and won't display current sale prices or descriptions unless you go in and add that manually.
Again, it's probably low priority, but as I add more and more stuff I realise it's maybe not ideal to have people see my games alongside software for 3D artists when I link to my profile from off-site? But I don't want to hide all that stuff either ^__^;
