Provide option to hide the app name and move the action bar higher on screen

[Ben-ADFA]

Ref. 4000

Please provide a way to hide the app name on the editor screen (e.g., in the screenshot below, please provide a way to hide "My Application1"), then move the action bar higher, thus providing more room for editing.
