Hi Janus. You’ll need to tweak some of your theme’s CSS. bbPress doesn’t currently have a ‘dark-theme’ permutation, so you’ll need to do it yourself, or enlist the help of someone that’s willing to do it for you.

As far as the reply heights go, your theme is applying some comment styling to your replies. bbPress 2.1.2 comes with some extra CSS to prevent this, but again it’s a CSS issue that you can fix yourself.
