I am a big JIRA fan, but lately they have dumbed it down to be very much like Trello. So I hope this gives me old JIRA back, built-in. Currently I have the "classic" workflow as an export that I can import. I wonder if they will try to push Trello users to Atlassian hosted JIRA Software with the simple workflow, or if they will combine the two like they did with Bitbucket and Stash.
