this is a request to move the mailboxes shown when choosing the mailbox location condition while creating a smartbox under a per-account header.

Thanks Cas, this whole screen is getting revamped along with how mailbox filters work. Right now filters match on the name only, regardless of account. To that end I’d suggest using Mailbox Type filter with an account filter.
