Ok, thanks! Then I didn’t just imagine that 
I think for the most part, it will just require a bit of time to get used to it. I do feel the entries in the thread list are a bit large now, though (according to Chrome, they are 18.4px).
And unfortunately, stepping everything down by one step in the settings is too small again. Maybe it would be worth having a more granular control? 
(as you say, on sites I control, I could adjust the theme, but on those where I’m just a member I don’t have that level of control)
