Thanks all so much! I think the areas I'm struggling with are:

1. I want to browse my own content in a format a little friendlier then the poser library structure. Classifying it in the categories I choose and tagging it the way I want.

2. I want to browse my "wishlist" in the same exact place/browser that I browse the content I own. That way, I can puruse all of it when trying to figure out what to put in my next scene.

So - like, here's what I've done so far. It's sort of Pinterest for my 3D content. I create lists of whatever categories I want (e.g., Scenes, V4: Clothes, M4: Characters, etc). Within lists I have both the items I own AND my wishlist items. I can tag everything to find - for example, all the Steampunk V4 Clothing. I can also see what/filter on I already own so there's no confusion.  

Oh! And the thumbnail images are nice & big so it makes for easy browsing. 

So here are my lists:

 

And if you click in you see all the content for that list with tags at the top you can filter on:

 

I like this because now when I like something I just add it (I've got like a "pin it" kind of bookmark - like pinterest, to add content I like from it's webpage) and I only buy it when I'm ready to render with it.

 

Is anyone else doing (or have you seen?) anything similar?
