Ability to archive Goals and Initiatives to hide old ones.

When starting planning for а new time period it would be great to put old Achieved and Abandoned Goals and Initiatives into a place that doesn't interfere with new ones. 

At the moment achieved Goals still show up on the effort/value graph and can be filtered only when selecting "In Progress", however current time period might include Goals which have not been started yet. 

A possible solution could be an "Archive" action and introduction of a filter that spans beyond just "All" and "In Progress". Making this filtered view showed by default could present the desired look at what is planned.
