Incorporate workflow functionality of the Jira Suite Utilities plugin into Jira proper.

It is necessary to use the plugin Jira Suite utilities to create a customized workflow for my company. It would be great if the functionality it provides were added to Jira proper. Frankly, I am not sure how a halfway complicated workflow can be created without this functionality. Specifically, the ability to set values for customfields and to set conditions based upon certain values of customfields.
