So a few things:
I find the contrast on dark mode to be pretty bad. The color for posts is slightly gray instead of white which simply is harder to read on an already gray-ish background.
And secondly, I personally only use the recently updated threads to actually use the forums. Is there any way we can make a better distinction between unread posts vs read posts? Sure, flarum did it in bold, but it felt like it was a stronger bold. Also, the unread post count lit up with a number of new posts as an indicator as well.
Also, the "threads that match your title" is listing threads that are 100% irrelevant
