Can I get rid of Smart Mailboxes?

Nothing happens when I control-click.

This is what I see . . . note that all boxes have been collapsed for security reasons in this screenshot. There are 7 inboxes.

Everything under Favourites is what I use.

Half way down you can see the title "Smart Mailboxes" with my 7 email accounts repeated.

When I hover over each one I get to the right a + sign in a circle and a disclosure arrow.

Control-clicking on any of the mailboxes or even the title "Smart Mailboxes" has no effect.

Note that I am on Big Sur.

One of my accounts is Google.

When I expand it, there is an extra heading called "Important".

If I control-click "Important" I get this window with a delete option.

However, none of the other mailboxes has this "Important" heading and control-clicking on anything else results in a pop-up with fewer options and no delete.

Thanks for the information Luis.

Reading between the lines it looks as though it is impossible to delete the smart mailboxes . . . the best that can be done is to minimise them which is what I had done.

I object to even seeing the name of a smart (stupid) mailbox but it looks as though I will have to learn to live with it.

Only the Google mailbox hd that "Important" folder that could be deleted.

None of the other 6 mailboxes had it and nowhere could I find anything to control-click that would give me a delete option. Every single one displayed this type of window.

Sorry to be a PITA but I think I have got my head around the problem at last.

I never had any Smart Mailboxes . . . just the meaningless heading with my proper mailboxes residing by accident below it and I was mistakenly assuming they were smart mailboxes!

I have now deleted my Favourites leaving just the original mailboxes with the empty titles "Smart Mailboxes" and "Favourites" below them as in the screenshot below.

There is just one big problem which must be incredibly simple to solve but is completely eluding me . . . I can only view the emails in one account at a time.

How do I amalgamate all the emails from all my accounts into one mailbox so that they are all displayed simultaneously?

Note that I have collapsed all the accounts so no mailbox/emails are displayed for security reasons

You are not understanding me.

I know about the disclosure arrow and there are no longer any Favourites because I deleted them last night.

I would like to create a mailbox to house all my accounts without creating any favourites or is that impossible in Mail 14.0?

It certainly is not in Mail 13.4 on my Mac mini where at the top of the left column it says "Mailboxes" and underneath is an "Inbox" which when opened up reveals all 7 of my accounts and not a favourite in sight. All emails from any of the accounts appears in the next column. Like this . . .

Thanks. Got it but you said hover over the >

I had to click the + sign in the circle to create a favourite "All inboxes".

So essentially I have been trying to do something that is impossible in Mail 14.0 . . . I suppose some people think that is progress.

I am not concerned with the Google account. All the other 6 accounts have similar boxes except for the "Important" one.

Every one of the 7 mailboxes above the "Smart Mailbox" label is repeated under it. So what are they?

Yes, I can minimise each one to a one line name but I can't get rid of them. So I will have to try to ignore them.
