I have been using this since it was in early beta ... and have to say what I used this week has moved on so much from the early beta version (of only a few months ago).

The team are listening to feedback and really creating a great solution for users of Jira that need to get shit done.

Disclaimer: I do know Dan and Hannes the creators of this plugin. But as a long time Jira user, they really have something here that is entering daily usage for me
