The new snapping in release 10 gives a clearer experience and more control in some areas, however, it also reflects a loss of control in other areas. This works perfectly for data sets with limited layers, however, to use snapping with a large number of layers snapping can be a bit overwhelming. We would like to see an expanding of the 10 snapping environment to make it more in line with other tools in ArcGIS and to include positives from 'classic snapping'. What we have in mind is to create snapping environments that you can save and load like layer files, that would be specific to include or exclude layers from the options. This would cut down on the amount of calculations that ArcMap must perform in a crowded or dense drawing situation and a better user experience. This way if I need to edit my electric data set or a base map data set, I can load the snapping environment that I desire and the version 10 snapping will only respect only those feature classes that I need. The new snapping is much better than the manual classic snapping, however, providing layer options in the version 10 snapping environment would help make the new snapping more complete and help classic snapping move on to retirement.. The import / export of the environments would only make snapping more versatile for users of ArcGIS.
