I like the way Codea (has it an official name already?) manages projects. The top section is for “read-only” projects which user can only play around with them but isn’t allowed to save the changes. And the bottom section is for “on-progress” projects. I think it needs a mechanism to move a project from bottom section to top section, say for a finished project. Yes, it will get messy if you get plenty of projects. This problem can be easily solved by folder mechanism, using Apple’s standard gesture and behaviour for folder.
One more thing, please add feature to rename projects. This seems to be simple, but sometimes it’s important. Btw, how to add description to a project? Is there a special syntax for that? I tried to find menu/button for such function but I got no luck.
