Ah, now I see: in the light theme, the unread messages are indeed white. But in the dark theme, the read messages are grey and the unread messages are even lighter shade of grey instead of black.
Anyway, here is a list of little tweaks that would, IMHO, make the users of no Unified Inbox like myself (maybe make them depend on the Unified Inbox being not set?) much happier and hopefully not break anything else:
- Make the Back button in the Inbox view show the Accounts Overview pane (see my first post) instead of quitting the app,
- Tapping the account in the Accounts Overview pane would go directly to the Inbox (saves a tap in switching accounts),
- Show the little color bars everywhere – not just in Unified Inbox – so that it is immediately obvious what account the messages belong to.
