Box before received letters

Now when I want to delete received mail I have to mark the letter and then push “Delete”.
Idea: make a box before received letters. When I want to delete letter - click the box and push “Delete”. So the letter will be deleted without being read.

You can also right-click on any message in the message list, and choose Delete, This deletes the message without being read.

Perfect !
Thank you !
