Thanks for the suggestion @skoczy, it would work if I only had the rig packs, but I've got loads of one off rigs from the exchange that would get mixed up in between. If you could do folders for an amp you could also put in profiles of the same amp from different profilers where the naming convention is different, and still have all profiles for one amp in one place.
When I browse rigs my thought process starts with "what amp do I want to play now" and not have to remember the way a rig was named, which is often started by authors name and not the manufacturer or model.
The KPA is an amazing product, in terms of features there isn't much that I'm personally left wanting at all at this point. In my opinion the only things that really could do with revising now are interface based: this, only displaying fx presets for the load fx type, and being able to filter rigs by additional tags such as studio, merged, DI/DA, guitar only etc.
