Yup, that's exactly it...

In fact I think that there will be so little to be shown that it doesn't really need an entire edge of the window to be holding the UI (like how the bottom command bar or side pane work in the main window currently), and it would actually be kind of weird to have that since it would be mostly empty.

Instead I think that UI would be something that was actually a small island piece that was actually contained within the view panel itself, similar to the way the view controls work currently (the Area / Zoom / Pan / Rotate / Reset toolbar at the bottom of a viewport).
