Glad to see the plugin has worked for you. Always good to hear.
The Calibre team has made it a very easy to add plugins. And code from other collection programs along with kiwidude's examples made getting started possible. This isn't the only way to manage collections so I hope the other programs not requiring Calibre continue to develop.
As for the great Plugin Updater, that's all down to kiwidude so he's the one that deserves the thanks
