UCP is trash.

It made message walls extremely hard to find, and completely ruined how comments work. You can't even use wikitext or even edit your comments, which I find extremely stupid.

Infoboxes are very hard to use, due to you having to constantly click those fields to actually make them show. I don't get why they thought that this was a good idea, as it only makes editing a page even harder.

One more thing.

Why do you always go into source edit mode when you click on a redlink to edit?
