Hi Ed, I know this was a long time ago but I would very much like this feature to be made available. When I map a parcel as a forester, I have to create many polygons within the parcel which denote individual forest/land cover types. The challenge I have is it is not possible to line up the vertexes of each polygon I create. This results in the final map being rather disjointed with the lines denoting individual stand types being slightly off from eachother. This not only makes the map harder to read for my loggers, it also makes the map look unprofessional like I just took an aerial photo and drew on it using a draw program not actual mapping software. In addition this makes it very hard for me to come up with acreage calculations that are in agreement with the acreage of the parcel due to accidental omission or duplication of area contained in the polygons within the parcel. This software seems to be the best option for the majority of industrial foresters working for small to average sized mills or loggers. Could you please reconsider adding a "snap to" vertex, or line feature please.

Version 9.5 has a reworking of the way tools interact with existing layers on the map. This new version is being tested right now, and should be available in the coming weeks.

While this particular feature is not part of that overhaul, I'd be interested to know if such a function would still be desired once the new release is live.
