Auto-trace plugin might be of your interest as well. It's ready and should appear in QGIS plugin repo soon. Cheers, Saber

I also think this should be in the core of QGIS - or before that it would be nice if it could be integrated in Bernhards Ströbl DigitizingTools plugin. I hate it when I have to enable 5 different plugins to get a decent digitizing environment. And when I teach QGIS to new users it is most confusing if functionality is spread among too many plugins. So if possible - please integrate such functionality in existing plugins or into QGIS core rather than starting a new plugin. Thanks a lot for your efforts.
