I don't understand this mentality. It's an email client. There's not a lot needed UI-wise to make a functioning interface. Display a list of emails, show the full message when you open it, etc. I don't see anything functionally different between this email app and basically every other one I've ever used.
You've either got insane standards or are using email way different than I.
Can’t speak for others but for me Thunderbird’s UI feels distracting and almost grating in some ways. It’s technically functional but doesn’t feel right.
I know things like that don’t bother some folks and that’s fine, but others like myself can’t turn the visual parts of their brains off and so some software feels like nails on a chalkboard to use.
