I guess this one doesnt exists yet...
The idea is to order categories by popularity, this can be measured by the number of hits in that category or by the number of downloaded files in the category, then order them horizontally instead of vertically
1 2 3 4
5 6 7 8
and not:
1 3 5 7
2 4 6 8
This would be very interesting for the users, I guess, it would work more less like a category top.
