Powerful

The free version is powerful, and the paid version is even more powerful.
This plugin completes my need for advanced functions, and makes it really easy to make other plugins work together without spending time on making a custom solution.

This plugin is now an essential part of my workflow, and it has made it so much easier to fulfill client requests to make stuff talk together. Now my fluent form can trigger events in other plugins that would normally not talk together, and all this without having to write custom hooks and filters, which would take a lot more time.

If you dont have it, you should get it.
