I have setup SyncDocs to sync only certain collections in Google Docs.
This is mostly working - however, I am finding it is syncing all docs that are not allocated to a collection in Google Docs. There does not seem to be a switch to stop it doing that.
As a workaround I have set up an 'Unallocated' collection in Google Docs (that is not setup to sync) and dragged everything that is unallocated into that.
It would be easier not to have to do that and to have the option of switching off syncing for any documents not in collections in Docs.
