I have 12 Runtimes plus 13 (12+1) Readme folders now.

I've been doing what Acadia said above:   create new runtimes, regroup folders within folders, and rename them in a way so I can easily recognize the items.

I also save readme files in the respective readme folder I created inside each runtime, plus in an overall readme folder.

In addition, whenever I purchase and download a package, I'd download at least one thumbnail or promo picture showing the product's name on it, and save it in a "product pics" folder I created inside each runtime.    
I rename the picture file to match the package or item's name, and regroup them inside the product pics folder as well.   

So whenever I want to pick an outfit for my V3 character for example, I can use Windows browser to quickly browse the pics in the "product pics" folder in my "female outfit" runtime,   and clearly SEE what options I have for her.
