PDF.js severly lacks a "hide toolbar" option

[celmir]

I'm sorry in case of this being a duplicate; I couldn't find this exact yet generic issue. 

It's unbelievable to see how pdf.js has so many additional wonderful features but yet you can't hide those options for when needed and have a zen-mode pdf viewing experience with non-presentation properties such as viewing the pdf by its page width (or almost any other feature except page navigation)

I miss this too and made a bookmarklet that hides the PDF.js toolbar:

javascript:void(document.getElementsByClassName('toolbar')[0].style.display = 'none'); void(document.getElementById('viewerContainer').style.position = 'initial')
