Isn't Remine Backlogs looking just amazing? Oh yes it is. I fell inlove at the first sight with its displaying of users using different colors, and I've decided to create a greasemonkey script that would bring the Jira task list at the same level.
So here it is how JIRA used to look before:
And after the greasemonkey script ran.
A known bug is that when changing the user for a task, the color for the current task does not change. The reason why this happens is because they don't refresh the whole task, but they just rerender the name. So if you want to see the updated color, simply refresh the page.
