Create and order, reorder mailboxes in macOS Mail
I want to create some new mailboxes in the Mailboxes/Inbox column, like I used to do every year, and order them, alphabetically or manually.
However, new mailboxes can now only be created and ordered at the bottom of the left column, below 'On My Mac'.
Interestingly, I can add and order mailboxes via the webmail interface. The new mailboxes are showing up in Mail, but are not showing alphabetically. They are put at the bottom of the /Inbox list.
I don't understand why, since this used to be a matter of right-clicking. I can't reorder existing mailboxes either, which is fine by me as long as they are listed alphabetically, but I can't.
I can't find a solution online either. There are reset instructions via Terminal but the seem to no longer work.
Mac Pro, macOS 10.14
