Drag and drop to email
When working on an Excel file I would like to be able to just drag it over and drop it in an open email. Right now I have to close the file then select add attachment. Not the end of the world but it would be helpful to be able to just drag it over.
If you edit your quick access bar and add "document location" you can copy and paste that location into the text bar once you select "insert file" in the email.

Another option is to go to the location where the file is saved, then select it. Press CTRL+C, then go to your typer email and press CTRL+V.
