Apple Grew has released the latest version of his Vert2Face script. The concept is simple, but its effect on you will be beyond words.
From the Blender wiki:
SHIFT-F. Fill selected. All selected vertices that are bound by edges and form a closed polygon are filled with triangular faces. Holes are automatically taken into account. This operation is 2D; various layers of polygons must be filled in succession.
The Vert2Face script (.zip) does something similar… but better… a lot better. Check out the thread for more info and previous versions.
