its more than the holy grail.. lol
I have allready looked into it..
its feasable but it implies a real complete rewrite of many parts.
because the last id is saved but not the file name.
so if you dont want to have and extra query for each displayed cat.. (some have more than 500) we would have to modify 1. database, 2. modify every query where cats are saved, 3. every bit of code where categorycache is used.)
It will be included when a major rewrite is needed but certainly not for the moment.
