If you’re anything like me and have a ton of downloaded styles, you probably get confused by which ones you’ve already tried and what ones you like the best. I think it could be useful if there were sorting options, so you could sort them by “date installed”. I’m constantly trying out new themes but by the time I install a bunch I get confused on which ones I just installed. Could also add other options, but that’s the one I would find the most useful. Just a thought 
Actually no, I’m only left with a couple of valid choices and mostly only use one… you’re pretty much an extreme ‘edge’ case in that regard…
Maybe if you avoid ‘installing a bunch’ and just grab them one by one, removing ones you don’t like, until you have what you need.
