Hi Mauricio,
Thanks for ask to the community. I have troubles with Human Task Module and generally was because of the lack of documentation, both tutorials or guide an inside the code too. So I vote to improve javadoc would be 9.
Another feature that I like is (I don't know if is relative of HumanTaskModule):
1) Support human task expiration with disposable session, out of box: priority 10.
Thanks!
