A major addition to this release is the firebug debugger support. The ZIP Download now contains a firefox extension that when installed with firebug allows you to send PHP debug data directly to firebug! Please see this post for more information: http://www.litfuel.net/plush/?postid=164
I will be documenting exactly how to play around with the mybic debugger. The basic overview is that you'll be able to call the $mybic->render() function and have a nested tree show up in firebug with all your profile and debug data. I've been using it for the past month and it's saved me a ton of time. Enough with the var_dumps!
get it while it's red hot!
