There's definitely some features I'd like to see as well. I mainly access Lemmy using a desktop browser so that's my perspective.

Foremost for me is a compact view. I'd really like to be able to view more posts on a page using a much smaller font with no extraneous line spaces.

A tip box that shows content when hoovering on a post would be great for me.

The ability to group duplicate communities would be a big help.

A setting to open all links in a new tab would make navigation easier. There's middle mouse and context menu on right mouse, but I'm so used to left mouse I can't beat the habit and constantly lose my place.

I need a global default for my sort order, or more granular options. You can specify it from the user settings, but it only applies to the front page.
