Dragging over a note's text on Dashboard now selects it, so it can be copied as usual. A click still opens the note, unless it leaves text selected. Right-clicking a note, or pressing and holding it on a phone or tablet, now offers Copy text, which copies the whole note, with Open in Notes and, for notes you can move to Trash, Move to Trash. Before, dragging over a note picked up its link, and the menu was shown only for notes you could move to Trash.
