After you disable an extension, you most probably also want to browse via ftp or your host cp to delete the extension files.
But you have troubles doing that as you have no clue what user made that extension and you will either have to browse all ext/ folders to find out where your extension is, that is of course if you are a little dumb and dont think to check in the Extension Details, in the acp.
But that is also not very fast and efficient. You shouldnt check for details to see the path to where it is installed. It should be right there, besides the extension name.
Dont think this would need a new Clean Name row.
Just add it in the right of the extension name between brackets. Should be easy to pull the data there.
