Also-also, turns out TB/BB's "dark mode" setting doesn't work either - and please don't ask me to add a theme or whatever, because have you seen the Thunderbird theme page? It looks like fucking Geocities, I haven't seen websites like that in the wild since the 90's, which of course makes it almost un-navigatable, but also doesn't exactly inspire confidence as a place to look for better design solutions...
