I already made a proposal to improve the default theme, but my issue was closed without any response from the developers. The required changes were small on purpose and should be easy to implement for anyone already familiar with the code. So it seems that UI is not a priority to Lemmy developers. That’s why I had to develop my addon, which I then also turned into a theme. I hope that one day Lemmy instances will start using some kind of modern theme (doesn’t have to be mine), so that my addon is no longer needed.
My theme is just a small amount of styles applied on top of the default litely and darkly themes, which should make maintenance easier. Unlike an addon, a theme doesn’t need to support multiple versions of Lemmy at the same time, so we could simplify it even more. Lemmy 0.18 uses CSS variables now, so that also makes things easier.
Something needs to be done about Lemmy’s outdated UI and I’m not sure if the current approach of developing multiple userscripts and addons is efficient. I understand if you think this might cause too much work for you though.
I don’t know the developer’s exact intentions, but my issue was a specific, easy to implement proposal. It wasn’t meant to be a discussion.
There have been UI improvements, but the design is still outdated. The theme you linked to is also not a modern design. What we need the most is an improved default theme, so that everyone could enjoy an easy to read website.
