As for whether the top bar needs to be floating, that I think @baris and I are of two minds about 😄
I think there doesn't even need to be a floating top bar at all...
Right, grand so let's find a way to get rid of it (more back to this point will follow), here is one reason why:
That's a whole topic listing used up by the toolbar!
... but I have a heavy emphasis on promoting the "reading" aspect of Harmony/NodeBB. This is why Baris added the "sticky toolbar" theme option 😉
I need to test out that stick y tool bar, bu on the other point, I'm not totally following how this manifests, exactly what do you mean about the "reading emphasis" - I will say the font and formatting is much improved, some feedback on that later, but is that what you mean?
