CCC UI changes not for the sake of changes, but to fit new features that are being implemented into it
From a small little forum, the community has already grown into a complex big system even with its own server.
Implementing even small features now bares the risk of breaking some other previously requested features. Same here, do you really think that it’s easy to fork two UI interfaces and keep them up-to-date facing the same issue that the new UI solved?
Same with many other requests, like keeping username changing allowed permanently. People do not quite understand the issues it will cause in load speed and DB re-write.
