This post lacks constructive feedback. Just complaining - without proposing any solutions or fully describing the issues - is a smooth-brain move.
Personally I like the UI changes. I no longer have to zoom the page out to get a decent font-size. Comment-collapse buttons are now on the left so it’s easier to collapse comments as you move down the page.
I would like to see a bit more indentation for comment replies. Currently scrolling down threads where many comments have single replies, the replies have more highlighting that the comments themselves, and the indent margin isn’t quite wide enough to obviously set replies apart from top-level comments.
However, all of my comments could be easily fixed with CSS in either a theme or with a user-applied style.
Meanwhile the original game is stuck with rockpox for 8 more months.
I do not enjoy the rockpox.
