We're using SCRUM for managing our project and one of the key concepts in tracking the work is that it's ok to increase the estimated time remaining for a task. For some reason Jira doesn't allow a value to the time estimate that's greater than the original estimate.

Please remove the constraint from setting the value to remaining time OR make the constraint configurable.

(I can see the Original Estimate field below and am really tempted to enter five minutes as the original estimate just to prove my point. Leaving it alone though...)
