Can I extend the work item UI?
One answer
Eclipse allows to do all that. Dependent on what you want, the approaches differ. There are multiple extension points for actions, context menu extensions and the like. Yari and plugin spy allow you to locate classes and find extensions. One example is here: https://rsjazz.wordpress.com/2014/02/21/adding-context-menus-for-jazz-objects-to-the-rtc-eclipse-client/ .
