Duplicate the same content tab

This is simple, but it's a two-step process.

First, from the hamburger menu, select "New Content Tab."

 Then, while that new Content Tab is the active tab, go to the "Reveal Recent" in the icon tools in the top left

 After pressing (and holding), scroll down to the folder you were last in. This will give you two content tabs of the same content. Note also that this lets you access any recent folder.

Let me know if this was what you were looking for.
