Document Information Tabs

While dealing with the file upload methods (discussed in another thread), I did an example of the info tabs as a floating panel.

Panel opened on to of the document

Resizing the floating panel

The same panel when the user reaches the bottom of scroll. This is the current implementation in XS.

I believe this is a good option when dealing with tables and other types of content that need horizontal space. But not so much for information that needs to have better context with the content, like comments.
