First I just wanted to say thank you for the work that has gone into this application. Nice work!
Second I was curious about the specific differences between the Free and Enterprise versions of FreiChat. We mostly use the Chatroom feature so I spent some time to customize it to fit with the style of our site. How is the Enterprise version "Fully Customizable" beyond my manually editing the CSS files? Also, does Enterprise have a different chat room? It looks like the Free version has an old version provided?
Thanks again and keep up the good work!

The js file is compressed in the free version preventing you from customizing it except for the styles using css.
Currently we have updated the chatroom to the latest in both versions due to major updates but normally it is always a few versions old .

There are other differences like caching , no powered by .

Thanks for the clarification!
