What is the name of the extension for Google Chrome?

Question

Google Chrome

Hello.
Somewhere on YouTube I saw an extension for Google Chrome that hides / shows all application buttons on click. The extension button looks something like this: upload.wikimedia.org/wikipedia/commons/b/b2/IEC500...
Googled for queries like toggle chrome extension buttons , chrome hide show extension buttons, etc. - didn't google.
Tell me what it's called, please. Thanks in advance.
