A good idea would be to make a little database of known bsa and its rispective esp/esm file to detect if the archive really needs to be registered or not.
The tool checks the list and the Morrowind.ini to see if the plugin is active and automatically removes the archive from the list if it's not.
I need the BSA archive and the name of the plugin that uses it.
So far we have:
