This is very nearly a dealbreaker. The look and feel of your KB is the heart of your brand to your customers once they have signed on that dotted line. Even as simple as letting you apply one theme to your homepage and a different one to your article pages would be a start. As is it looks like I built my article content in a new system and built my navigation bars in 1999. Please bring this in line with the rest of your great customization.
Also… when our KB can’t look as good as your own there’s a challenge… Support couldn’t help me even mimic what we liked in your own versions.
