All performance improvements are available in the current public version of the game. You can use and try them out right now. In addition, we don't know which main page it's about (everything seems to work). As for the suggestions: we will consider them and thank you for the initiative to tell us what you are missing. I think quite a lot has changed since the release of the new versions.
Thanks. Ok, that's strange then. For some reason the comments on your top page just up and vanished for me one day. And only on your page. All the other games I follow are fine, so I'd assumed is was something you disabled, for some reason. It doesn't appear to be an adblock-related problem, either.
Looking into it more carefully now... it seems to be related to my browser (Firefox). It's there in Chromium.
No, even stranger, it's there when I'm logged out, but gone when I log in. In both browsers. Now what could be causing that?
