Hi Dev list,
Is anyone aware of a plugin that can:

 * auto-snap (make concurrent) borders between adjoining polygons
   (perhaps also in different map-layers)
   (Like topologically aligning cultivated land polygons with river
   banks or other adjoining polygon features)

 * auto-snap (make concurrent) polygons borders with line features
   (perhaps also in different map-layers)
   (Like topologically aligning cultivated land polygons with road or
   other line features)

 * Drop in vertices at places where features intersect each other
   (perhaps also in different map-layers)
   Like a road crossing a field (but not dividing the field into two
   pieces), or a bridge feature running on top of a road feature
   (placing vertices on the road feature directly under the start &
   endpoints of the bridge line)

It would be cool if this could be automated, with the ability to set snapping tolerances, and choosing whether to have a master feature set to move to, or to average the gap between the features (ie: move both features to the averaged common boundary). The final result must have identical vertices in both the adjoining features even if they are in separate maps, and the ability to set a master (aka unmoveable) feature is critical in case you need to align more than 2 features (eg: Municipal boundary with cultivated land with road), as you would not want a previously aligned feature set to "walk" whilst you are aligning a further feature set to it.

Thanks & chat soon,
Zoltan
