A recent thread with a new user involved troubleshooting masse install of add-ons, related to prerequisites for an “advanced user” add-on that was of no use in his setup.
Could a prerequisites list be added to the registration items?
And perhaps a flag for those that require configuration after installing? (Like the Place Cleanup addon that requires signing up for a GeoNames webservice and adding its password to the add-on configuration.)
This would allow the Plugin Manager to filter out Plugins that offer too many complications for basic users.
An “advanced user” flag might also be nice. Most users have no need to see alternate database engines or the Cairo Clock developer sample code.
