There are a number of exciting features in our upcoming release. One of which is the remake topology tool. See this video tutorial by kattkieru ( Charles Wardlaw) that shows the basic function of the tool including the paint based and mesh based retopology.
As can seen by the sample image with just a few mouse strokes, one can quickly make a new topology over a preexisting mesh. So watch the video, read the tutorial, and learn something really cool.
