I think the only thing that’s really missing for me and not just from old.lemmy.world but from the normal Lemmy UI. The ability to have clicking on links open in a new tab. I don’t know why but I just really like having stuff open in a new tab so I can then come back to exactly where I left off.

Middle clicking a link (clicking with the mouse wheel) or ctrl clicking, opens links in a new tab.

Middle clicking also closes a tab of you middle click on it.
