With the Agile Remaining Estimate Counter add-on you get summarized remaining estimated time by particular group of tasks.
This Atlassian Jira plugin allows you to see the total sum of remaining estimated time even with tickets’ subtasks in the sprint list.
AREC shows total remaining effort for partially completed issues including Sub-Tasks.
AREC Jira add-on calculates correct remaining effort in the same values as used for “Estimate” in Scrum or Kanban boards: hours, story points, issue count, or custom values.
AREC reflects effort for the whole team in both active and future sprints in backlog. Active sprint board reflects remaining effort split by swimlanes.
