I am not a tab hoarder, but I have been using Tab Groups as a way to collect (and hide) YouTube videos for future viewing.
I had previously used the Pin Tab feature to collapse them, but Tab Groups allows you to have essentially unlimited videos that only take up a single favicon-sized space when collapsed.
As someone who somewhat does the same thing, I'd recommend just adding the youtube videos to playlists so that you can just close out the youtube tab and only keep the one with your playlist up. Like I slap all my interesting podcasts, tech videos, hobby related videos, conference talks etc in a "currently watching" playlist and it greatly cuts down on decision fatigue to just have it all thrown into a queue that you can just sit down and consume (with occasional reordering).
Interesting. Does this mean I should tell users to avoid pinning tabs when browsing in the Tor Browser Bundle? (Assuming they have set the slider to "safest" to disallow JS)
