Description

Sorting issues by milestones should distinguish the milestones by opened and closed milestones.
This would improve usability, since one rarely searches/filters for issues of already closed milestones.

A separation between opened and closed milestones is already done when selecting a milestone while creating an issue. I think the UI there is good and should be reused in the issues-overview page.

+1. Today I found out that closed milestones are still listed in the 'Issues' page filter box, I expected them to disappear from view once closed. Because of #4984 old milestones will now forever be in the way at the top of the box.

I think we should either:

• hide closed milestones except for the 'Milestones' page where you can retrieve issue lists for closed milestones; or
• separate milestones in filter boxes into categories as suggested here, with closed milestones at the bottom.

@bugreport0 , #4984 was fixed by #4987 already.. It would be in the 1.6.0 release
