Teachers like the sidebar block as good alternativ for an overloaded section zero. Section zero is using section 1000 (and higher?) for storing resources and activities.
But when they try to make a backup, section zero is not in the backup/restore.
The point is that during a backup/restore new instances are created of resources and activities which you need in the backup course.
"Import from another course" WE LOVE THAT NEW OPTION!! also doesn't see the sidebar block. (Most other blocks don't have dynamic content, so recreating them is not that hard..
Who comes with a clever trick?
(I think now only of a workaround to give section zero a very low section/record number in the database, just before a backup starts..)
