The upcoming process repository feature (http://blog.athico.com/2011/01/process-repository-using-guvnor.html) is a very useful one as it can give the ability to business users to modify the processes.

It will also be nice to have the ability to load the task forms, associated images etc from a directory from the local file system.

The current process of including them in jar files (jbpm-gwt-form-5.0-CR1.jar, jbpm-gwt-graph-5.0-CR1.jar) is too restrictive.
