[Qgis-developer] (Yet again) SAGA support badly broken in QGIS

[Neumann, Andreas]

Hi, 

If you guys think about integrating SAGA closer into QGIS, could we also
fix the issue that SAGA is currently limited to reading Shapefiles for
vector input? Probably a lot of work - but would this be feasible? 

Greetings,
