We were able to use the plugin to construct a glossary from spreadsheet data we have. The instructions provided in the settings page to properly produce comma-quote delimited CSV were very helpful as well.
My only wish was that it was a bit more clear in that you have to manually add the glossary taxonomy/categories first, note down the categoryID, and integrate that to your spreadsheet data before importing. In other words, a more beginner/non-developer friendly way of explaining the process.
Otherwise, great plugin with rapid support response time!
