Ugh, don't get me started on email-clients. I haven't found one that doesn't do something that annoys me. This one looks promising though. I just hope it allows for IMAP-accounts and isn't Gmail-only or something like that.
Why do clients even do that? Get rid of Gmail! Use Fastmail or something.
Update: Marcel found a comment saying, that the v1 is a Google-only app. 🙄
