JSU features include new custom fields, enhancements to the Jira workflow (new conditions, validators, post-functions) and a new 'Transitions' tab on the View Issue screen.
JSU is also packed with powerful pre-conditions for post-functions that cannot be found in other apps.
The original version of this app was written by Gustavo Martin. Since 2011 it is maintained, improved & extended by beecom.
