Bugs in mail big sur

If it isn't finding anything, try rebuilding the Mailbox. Select a Mailbox and choose Rebuild from the Mailbox menu.

When you ctrl-click on the Toolbar, you can set it to icon only and remove the text which may be causing the expansion.

You may want to try this:

View->Customize Toolbar

and then drag the default toolbar. Maybe this will reset whatever is not working as expected.

Then if necessary you can work from that default to organize it to your liking.

I don't see any of these in my mac.

You can organize the buttons in your timeline in whichever way you like.

View->Customize Toolbar

then you can drag them around, add or delete buttons from the toolbar, add or remove spaces between them...

What happens when you click the search loupe?

Interesting, thanks for telling us. I wonder if the words in Dutch are longer and that’s the reason that the icons get further apart. I did notice that selecting Icon only or Icon and Text does not change the spacing, so my educated guess is that the text size determines how far apart the icons go.

I suppose it is a matter of opinion.

They seem pretty ok to me - but then I never use these buttons. It is much quicker to press the delete key on the keyboard.
