Topology level simplify tool

It would be very useful to have a topology-aware simplify tool.
A topology aware tool would simplify only EDGES of the topology rather
than full geometries. This would prevent those funny effects on crossborder lines
being simplified in a different way.

I saw the topology support is already in somehow, as the node tool is able to edit
multiple edges at once when moving a node.

Another alternative would be allowing for simplify tool to specify first and last point
manually (more work for the user but still less than clean up after feature-level simplification)

didn't someone do this in a plugin ? What was the name ? The feature request may be considered closed by such plugin...

This can be done with v.generalize GRASS Processing module

There is now Simplify coverage tool in Processing.
