On the web UI, something I'd like to see is the various front ends people are making to be folded either into a user setting where you can select from a list or provided as different end points like old.reddit or, as lemmy.world has done, m.lemmy.world, or as lemmings.world with old.lemmings.world.

There's wefwef/voyager, alexandrite.app (for desktop, using it right now, see !alexandrite@lemmy.world ), the standard, and I'm sure a few others that many would be happy to use right now. And it would be awesome if you could just use which ever you like whenever. Also a wonderful demonstration of what FOSS can bring to the table.
