We added an extra UI for our users. Photon by Xylight is an interface with a sleek, modern look and has all the bells and whistles you would need. Moderator tools included! You can access the UI from https://photon.lemmy.world.
Visit Photon's project page on github or get in touch with the developer in the !photon@lemmy.xylight.dev community. If you want to use photon on other instances you can do so from https://phtn.app.
This UI is very good for desktop users ,
It solves the problem of official UI . it does not makes sense to not show bigger images in posts in official web UI .
Thumbnail views are great when you are searching for stuff , not when you want to actively read posts while scrolling.
