</div>Hm, then we have three. I made QgsGeometry::validateGeometry(), when I needed<br>
to fix a bunch of polygons and found that the node tool refused to edit broken<br>
geometry at all.<br></blockquote><div>Hmm, ok, didn't notice this change. I'll have a look, and see if I can update the geometry validity tool to use this functionality. Thanks for the info Jürgen! Shouldn't be too hard to use this function, plus add some of the suggested features to make the tool a bit more useful.</div>
