Persist email filter option across sessions

(I see that one related issue is closed because of this one being resolved, but I don’t think they’re not quite the same thing)

It’d be nice if it could stay at what I choose recently (since I’m used to seeing all mails and I believe it’s not just only me!)

It’s a bit annoying when it reverts back to “Important“ whenever I navigate else where (like changing settings) then come back / start a new session / etc..
