It's a simple but very useful plugin, and it fully fulfills its purpose as a Chat Widget very effectively.

What I like most:
- Simple and easy to configure.
- The widget can be implemented on sites that are NOT based on WordPress.
- It has multiple and varied channels for customizing the widget (even FAQs 😎).

It would be great if BitApps expanded its customization options: the "Widget Style" only has two styles, however, it's interesting that we can add custom CSS, so that should be fine.
