My 2 cents: top menu goes away when you reduce window width; on mobile no menu at all (but content goes one column correctly, so halfway responsive). If you move or click on something, it highlights the cell (not everywhere) but there is no operation/command bound with that (no copy to clipboard or any kind of interaction). Usually, something highlightening represents an action that user can do.
