Please add support to read and write spatial data from a SpatiaLite database. ESRI and QGIS have supported this format out of the box for quite a while. We have a mixed use environment Alteryx, ESRI, Mapinfo and QGIS and would like a common file based spatial format. You already support SQLite, its container, so expanding to the SpatialLite spec should be a no brainer.
