Since we moved to the new software, a lot of the comments in the old thread will not apply. We have discovered that only part of the theme stuff transferred or has been rebuilt, and XenForo 2.x is substantially different. The former theme mod files are not the same, some plugin features have been incorporated, and for the moment not every addon has been enabled.
It possibly went by unnoticed, but the avatar image in the header has a slight border to distinguish mostly black avatars from the black background. Also recently changed is the theme selector link/button in the footer is a bit more visible.
There have been few adjustments to this theme thus far.
However, recently there was some additions of logos for the category headers and single category view. The single category view logo addition is something I had wanted to do ages ago but simply did not figure out the needed selector. I need to look into how I adjusted the Ganz großes Kino -dark theme to adapt to wider viewports, so that I can make an alternative New Style theme which works similarly for those who are okay with the glaring brightness but are annoyed at the inefficient viewport space use.
