Specifically, I've been expanding the north of the main continent out to the north-west and incorporating Færún's Sword Coast (from the D&D Forgotten Realms campaign setting) so that I can make use of Neverwinter and Waterdeep.
I started our 5e campaign with the Starter Set and its Lost Mines of Phandelver module (which, incidentally, we're nowhere near completing), and all the action in that adventure takes place on the Sword Coast. So, it seemed like a good idea to shoehorn it into my own world.

Adding roads is way easier since Photoshop finally started supporting dashed and dotted strokes on paths — I think they started that at long last in CS6.
