Feature request: swipe interaction to move to next account

Hi and thank you for this great app!
I installed K-9 a few days ago (v6.601, Android 8.0.0) and added 6 mail accounts.
As I personally don’t like the integrated display of all account mails on one page, I’d prefer a swipe interaction on the title/account bar to move between the different accounts.

Thank you very much,
