Plus I envision to have good testcase coverage for the whole system.  
I envision to have a clean core that shines through simplicity. I  
envision a non-viral component handling (One word:  
AbstractLogEnabled). POJOs and factories where feasible. I envision  
being able to drop block jar into a folder and extend my cocoon's  
functionality without configuring or doing anything else. (Maybe even  
at runtime.) I envision a cocoon where flow is not a 2nd class  
citizen. I envision a cocoon where your components like caches might  
persist. I envision log messages that are also understandable when  
you are not a core developer. I envision a cocoon where you have to  
write less.
