Recent ver 0.11.2: QGIS Export ist a really fine thing but: while project databases (former project.db) are now named specifically exported layers are not found in QGIS because target is ‘project.db’. One has to chase layers by hand so far.
Ahh thank you for the report…that’s possible. The export to qgis isn’t in the final state so we’ll focus on this bug in next iteration.
Issue is fixed in released 0.12.0 version
