I "use" to have an unused folder and then I decided to get rid of it because it hurt my brain LOL!!!! now I have my kits organized in to themes and I seem to use them alot more that way! I do have all of my previews for kits in a preview folder and alot of times I go there first
I usually know if I have used the kit or not buy looking at the preview
and I am with Elizabeth on having AWESOME CT's or I would REALLY BE BROKE
