Feature request: tool that can split polygons

The split feature tool is currently only able to cut polylines. It would be a really useful addition if there was an equivalent tool that could cut polygons, either by cutting two edges or by drawing a polyline that bisects the polygon.

Is something like this planned, or would it be too difficult to implement given how features are stored?

I think this sort of thing is possible if you use topologies, but having a dedicated tool for cutting simple static geometries could be quite handy.

Eventually something like this is planned - it becomes a little more tricky when the polygon has interior holes (eg, some paleogeographies). But something like this is usually low priority since you can use other tools for this (such as QGIS/ArcGIS) and then import into GPlates.
