Kanbanery for IntelliJ
Use Kanbanery as IntelliJ Tasks resource.
You can choose tasks from your Kanban board (or multiple boards) and start hacking on them.
Be sure to take a look at the README in the github repo, as it contains a nice preview of this plugin :-)
Task titles (and reference ID's) are then added automatically to each commit so Kanbanery will know that some commit is about some task.
You will need to create a Kanbanery account to use this plugin, but don't worry - it's free :-)
General usage instructions
Get an Kanbanery.com account and set it up in the Tasks -> Servers section of your intellij project configration.
There's a good guide here, on github: https://github.com/ktoso/kanbanery-for-intellij :-)
