I created an issue because I wasn't sure if this would work. https://issues.apache.org/jira/browse/SHINDIG-1697
I think it would be useful to be able to include CSS in features so you can include common CSS libraries so that containers can more easily roll out a common look and feel across gadgets. We've worked around this a bit using templates but the feedback I get is that it is awkward. This make sense? Matthew Marum
