I think one of Courtney's original original questions also asked what I'd ideally like my organization to be....
What I would really like, is my own "store" for "shopping" i think. I'm happy to have all my kits in designer folders and individual kit folders, but I struggle to remember what I have for using it purposes... so I need to start copying previews into a preview folder. I was going to start tagging things, but that isn't realistic, when I have 300 GB of stash to start from scratch. stuff from before my purchasing days (all those freebies I've downloaded but haven't necessarily purged yet), i renamed all sorts of random things, mixed together, moved... Also, I keep PSE (organizer) on my computer, but stash on my hard drives, and I move my EHD sometimes, so Organizer gets lost on my files.
My workflow right now is to download to my downloads folder, move into my scrapbooking folder, use "unzip them all", then as soon as that's done, I copy all the zipped files to the second hard drive, then move the zipped files to a spot on the computer's main drive. (this was not meant to last, but it's been in place since July - until I get a third hard drive)
Once the zipped files have been copied/moved, the unzipped files are in my scrapbooking folder (for the past month or so, at least, because my main EHD is full and I need to do some major cleanup)... when they finally get moved to my EHD, they are in their individual designer folders. Tagging is unrealistic because even if I tag what I have, everything is zipped in the back up places.
It's not so much that I need help finding something when I need it... it's not knowing what I have, in order to look for it anyway... Many times before TLP upgrade I would search for what I wanted and look for the green "already purchased!" thing...

that seemed to work for me, so I need to do that for myself. LOL
Though, I'm still trying to decide for sure how I want to store/keep BYOC and my M3 subscription files. I thought keeping the BYOC pieces with the designer's folders was working, but I always forget I have another option, and have been absolutely horrible about remembering to place the previews in the BYOC folders. Or any previews in any folder.
Bahhh.... in any case. Back to the original point. If I had my own "store" when I was working on a page, I could pull up all my previews, and "Shop". My idea is, if I keep a previews folder on my main computer, I can use Organizer without issue... it would only need to load my previews folder. I could tag those by categories in batches (i think) by designer, store, whatever. Then, i could search easier and see what I have... then looking at the preview, know exactly where I stored it.
