Is this a joke? All this discussion and that is everything, 60 slots instead of 30? How about more like, 1000? Is there any technical reason why that isn't feasible?
As already mentioned, Sandro discussed this on the Q&A and yes, there's a technical reason. It's a tad lame but basically I think it comes down to the fact that, because the UI currently presents stored modules in a long flat list, scrolling down a list of a 1000 modules would be impractical. Basically (and this applies to bookmarks and friends lists and group management and any potentially long lists of data), you need, at the very least, to implement some sort of folder structure (or better still a named/categorised/keyworded faceted search facility) if you're going to do this "properly". Since FD are too busy to do this "properly" at the moment (and hey, I understand what that's like) the quick solution is a flat list and a limit on the number of entries.
