I’ve seen many comments and posts regarding the API fiasco on Reddit, with the claim that there will be a huge influx of users when that happens. I’m all for it, but I find it hard to believe that the average or even above average user will make the effort to switch.
You’re misinterpreting what happened there - the issue was not closed to shut it down, it was actually converted into a discussion to make it easier to track: https://github.com/LemmyNet/lemmy-ui/discussions/1503
It wasn’t exactly one specific issue that could be fixed, it was a longer discussion with a bunch of branches. For such things, the discussions format is much more usable.
I just want to point out that there has been a massive amount of UI improvements in 0.18 and 0.18.1 (just take a look at all the changes by @jsit for example: https://github.com/LemmyNet/lemmy-ui/pulls?q=is%3Apr+author%3Ajsit+). In addition, new themes are being created directly for the lemmy-ui repo as well, for example: https://github.com/LemmyNet/lemmy-ui/pull/1682
