As some of you may or may not know I am a huge fan of the Fusebox framework. I have been using some sort of offshoot of it for about 6 years now. It really came around with v4.1 but 5.5 is going to blow everything out of the water! It is currently in public beta.

According to the documentation some of the primary themes are:

1. Simplify. Remove barriers. Make it easier for newbies. Make building applications faster by favoring convention over configuration.
2. Extend through extensibility. Provide new functionality outside the core. Add plugins, lexicons, even standardized circuits.

Go ahead and and give it a go round.
