LSNBLDR-316 Lessons was modified to create a configurable top folder in Resources to store all the uploaded files.
This nice addition allows teachers to hide this top folder so contents are available only through Lessons. Lessons doesn't respect the hidden visibility flag as it is described in
We think that the logical behaviour for this top folder should be to be created hidden by default. Or at least to have a setting in sakai.properties for allowing admins to set it as hidden.
