We just added Alexandrite to the server, it’s an alternative desktop UI for Lemmy created by Sheodox who worked tirelessly to make the necessary changes to we could host it ourselves here. So go to https://a.lemmy.world and have a look!
He continues to update it constantly, you can follow the development on his github page or in his community. If you like what you see and want to support him, why not buy him a coffee? :)
For those who don’t have Lemmy World as their home instance and want to use Alexandrite, either ask your instance admins to add it or go to https://alexandrite.app!
Edit: I should probably have mentioned that Alexandrite is meant for desktop!
There’s a slider in the settings for the hue used for all the background/borders/text etc, so you can change it from purple to other colors, like:
Eventually I plan on adding more customization so you can change the colors of links/votes, and I need to make a light theme because so many people want that too.
