Setting for single virtual root browser vs multi tab browsers

[vidartf]

Currently, each additional resource added to Jupyter FS creates a new side bar tab with its own browser. From a UX perspective, it might also make sense to have a single tab, but with a virtual root and each resource as a node at the top level. This might also make it easier to copy/move files between different resources.

I'm going to work on this next as I think it makes it nice to copy back and forth from local to s3

I've done a little research, im going to break this out into a few separate steps and link back here.

In our version of the UX, we have a picker at the top of the panel - recognizing that a whole named storage space is different conceptually than a directory. That lends itself to later folding in configuration into the picker section: new/edit button, etc.
