Delete button should never delete mailboxes

I select a gmail account inbox. I see a message in the preview window. I want to delete it. I hit the delete key. Em Client asks “Do you want to delete Inbox”. This would be a disaster! Please do not use the delete key for deleting entire folders. For managing folders the right-click menu should be used. When a message is open, the delete key should delete the message. This is also how Outlook (desktop version) works.
