The idea behind
The main reason for why this app was created was to show whole issue history visually on timeline, so you can get better grasp on how issue was changing in past. On timeline you will easily see how much time issue spent on each status, when it was transitioned, field changed or when it was commented on and by who. It really helps to easily get issue history information just by looking at graphical timeline, compared to raw data in issue history without any visual reference. Issue Timeline also allows you to view history of parent task or subtasks, so you can easily compare them, and see how they was changing in time in relation to the main task.
What's next for Issue Timeline
We want to expand standard functionality of Issue Timeline and add some more features. Currently we are aiming at:
better events grouping, especially when there are many events in small time period,
some more statistics about time issue spent on each status,
ability to filter events that should be displayed. After that we are looking forward to publish our app on Atlassian Marketplace.
