When in dark mode on my iPhone, if I get an email notice from a TidBits discussion and want to reply by email (using standard iOS Mail) something about the email formatting in the email I’m replying to forces the background AND the letters I’m typing in to be white. So it’s almost impossible to read what I’m trying to type in.
The fix is likely something that would have to be made at the Discourse level, so if you want to report the bug to the developers, it will flow through here once it’s in place because I install updates quickly.
I don’t want to jump into the world of a different email client. You probably are aware how obsessive I am about email client features. And iOS Mail finally got a message filing interface where you can tap at the top and enter the name of the folder to move to! Even Gmail in iOS doesn’t have that, which I think is weird, since Gmail is so into label.
I don’t use dark mode on my Mac, just on my iPhone and iPad. I could test though.
I hear you about late night device viewing. Off the top of my head, a few low-tech, inconvenient, work around options follow (none of which are ideal):
reduce iOS brightness (can cause difficulty reading text and induce eye strain)
use dark sunglasses
use “blu-block” glasses (only the seriously orange tinted ones really do anything, but that would cause more vision issues with color)
Just out of curiosity, if Dark Mode is on, does anything change when you alter your TidBits theme to Dark as well (as Adam mentioned)? There could be unexpected results depending on how each of those are set. Might be a helpful detail for bug reporting.
