Hi,
I've created application, which automates browser tasks, called BrowserAutomationStudio.
BAS uses javascript to control browser, but also has ability to record user actions as macros.
Besides actually browser emulation, I use CEF for creating part of user interface: scenarion and expression constructors, task list visualization.
Here is how it looks like:
Project is free.

And thanks to CEF team for this awesome framework!
