I am a kit scrapper, so organising on kits seems most appropriate.
I also have a special folder for templates, because without them I feel really naked. I have a folder for each template designer. And the ones from Cindy are also divided into 1 photo, 2 photo's etc. Just for easy searching.
Separate bought alpha's go in one folder too.
So I guess I am pretty good organised.
I like the idea of a not used yet folder. Because I have a lot of kits which seem great to buy but which I didn't use yet. With that new folder I can keep an eye on that.
