Footer panel or floating and dockable panels

An area along the footer of XD for a long panel.

Use Case:
James writes a plugin to display the selected node in SVG. He shows a preview of the SVG in the left side panel of XD but long rows of text are truncated and clipped by the limited horizontal space.

With the new footer panel he can now display the SVG text along the bottom of the application making it much more readable.

Alternative Feature:
Resizable floating and dockable panels
