The Problem
As you can see, I’ve selected a bunch of mail to delete, but on the right, where it shows how many messages I’ve selected, it doesn’t have any other options.
That really slows things down for me. Although it’s fine since I am not majorly inconvenienced.
Proposed Solution
Use the empty space below that message counter to add some commonly used mail actions.
Alternative Solutions
Just right click on any of the selected mail, the context menu shows what you need.
