make the top bar only one height (move / remove office online logo)

[ne0YT]

Is your feature request related to a problem? Please describe.
I would like if I had more space to edit a document instead of always looking at the office online sign

Describe the solution you'd like
some js code to hide the element would suffice for me. so I can just make it disappear in my installation.
but an option to tick in settings would be cooler :)
