Bookmarks lack anything visual to make me think "Oh you know what I want to look at that again"

and in the case of waiting for an upcoming stream if I forget the upcoming stream 8-12 hours later, then i'm usually pretty upset I missed it.

Sure you could just say "Well if you forgot you probably didn't care that much"...but my memory sucks and a lot of it is also meant to destress from a stressful day, which can contribute to forgetting things.

I have like 10,000 bookmarks and I only look at like 5 of them

Up until the web API stuff I was using opera, and it had like...a collage view where you could put a bunch of sites on, with pictures to represent them. That was nice to have. I couldn't find anything similar in the firefox extensions.
