Work Item Management Issues

Issue 1:

We are a small team and will mainly be working under one project. Can we please have the ability to remove work items that have gone to production something like an "Archive" button when an item is deployed to Production so it can be removed from the list and then maybe have a new tab beside "Activity History" called "Work Item History" where you can view all past work items.

Issue 2:

Some times when you get to a deployment stage like "UAT" and changes need to be done based on feed back i need to start this process over. something like:

1. Delete work item: then I would need to go and create a new one
2. Roll back work item to beginning so changes can be made then pushed through again
