Additional keyboard support for Esc which now works in any screen, returning the user to the links panel, and left and right arrow keys which flip between panels.

added an additional opportunity to hide the 'drop here' overlay
removed title
UI restyle (white) plus improvements to the small-screen view so that the buttons and search box rearrange themselves nicely when 'being responsibe'
