Save SHP with .sld- and .qml-files to preserve styles.

Saving as shape doesn't preserve styles from the project. Please add .sld and .qml to the zip-file.

Good idea !

Quickly thinking about it, I don't think it's easy, as it's first fetching the GML from QGIS server. It would need a dev in QGIS server as well maybe.
