I made an eliminate tool (similar to ESRI's eliminate). It dissolves
common boundaries of selected polygons and adjacent polygons with either
largest area or largest common boundary. If you have multi polygons you
would need to transform them into single polygons beforehand. The
eliminate tool is part of fTools in current master.

Thanks Sandro,
so that means that you get multi polygons with very small polygons created
when a auto-intersection is cleaned. I prefer that since it does not
destroys existing node. I think qe should add another tool after the
'makevalide' tool to clean those artefacts based on a surface threshold.
This is really hard to achieve for common end user, and those artefacts can
be really numerous if datasets are not clean. They also will make it harder
to edit a polygon manually, and will slow down spatial intersections.
Anybody else needs such a tool?
