Git Harvest

This plugin is a lifesaver! I use it daily for all client GitLab/Harvest projects because it simplifies my workflow, saves me time, and ultimately just works when I need it to. Not sure why Harvest doesn't have their own official plugin but this 3rd party option is rock solid and I couldn't recommend it more.

Good extension, needs better integration of the Harvest button in the layout of the issues pages and Jira support
