I haven't figured out how to get my item notes to show up with the items on the collection page, either. I think that might be a feature only available to Angie.
FWIW, I use the Closetspace app to track my wardrobe. It's kind of a pain to get started with, but now that I have everything in it, I find the upkeep and item tracking very easy. I think that's true of just about any system (analog or digital) that you choose.
There was some talk about detail-oriented vs big picture people in Sally's thread. I think most people, based on my tracking and the way I keep coming back to the data, would think I'm detail-oriented. The reality is, I'm quite the opposite. That's the reason I do the tracking. I can easily look at my wardrobe and know I have a lot of black and probably more skirts than I need. I get overwhelmed by and lost in details when I try to keep more info than that in my head, so I develop systems to help me. I suspect this has come about from the need to be detail-oriented at various points in my career, despite my natural tendency to gloss over the little things.
Also, it's fun for me...sort of a "gamification" of fashion, to try to wear all my new summer additions ten times, for example, or to make four outfits using one layering piece. It's a hobby.
(ETA: In Closetspace, I can tap on an item to scroll through all the outfits I've worn it in, as well as any I've just created and saved for future reference. I don't use that feature much, because I seem to like constantly reinventing the wheel, but it's occasionally made me realize something, "Aha! I don't wear that top anymore because the sweater I used to wear with it wore out" or something similar.)
