The tray lights up while a dragged widget would land in it
Dragging a bar widget toward the tray had only a thin outline as a cue. A change merged into quattro lights the whole tray while a drop would land in the drawer, and the tray goes dark once the widget is out.
Dragging a bar widget toward the tray had only a thin outline as a cue. A change merged into quattro lights the whole tray, the pinned icons, the chevron and the drawer, while a drop would land in the drawer, and keeps it lit while a widget dragged out would go back. The tray goes dark once the widget is out. The tray's very ends still drop beside it.
