Don't use CM Tooltip Glossary on a live site if you're only testing with dummy data or on any site if you expect an uninstall to remove plugin files and data from the database.
CM Tooltip Glossary will NOT remove the data from the database.
This could be a problem if you're moving from test to live data or if you have a very large glossary and decide to uninstall the plugin because the data in the MySql database will not be removed.
I must admit, I thought it was standard practice that all good plugins cleaned up after themselves. Apparantly not in the case of CM Tooltip Glossary.
