Hey guys!
I was looking for a solution that allows me to capture usage data from an app developed using the C2. I have discovered the Amplitude (http://www.amplitude.com), a very good tool to understand your users' behaviours!
The plugin is available in my GitHub in github.com/rafaelfl/amplitude-plugin.
This plugin allows you to log any actions performed by the user, passing parameters (or not) to the service!
Any issues, please let me know. :-)
Best regards,
Rafael.
