When you open a document in the Web Document viewer it opens a new tab in your browser and includes a back link in the top left corner. If you click back, it takes you back to where you can browse the folder structure. If you open another document, it opens a new tab in your browser, and round and round you go and end up with lots of open tabs.

I would like the option to be able to disable the Back button in the document viewer to help prevent this.
