Have you tried checking out Sky Follower Bridge? That's what I used when I moved to Bluesky. It's an extension that checks your followed accounts on the Bird app and looks for them automatically on Bluesky. Made switching 100x easier for me

Honestly if they add Bookmarks I think I'd be done with Twitter entirely. People here are genuinely 1000× nicer, and it seems like real people rather than bots/onlyfans ads
