It would be consistent (with other edit views) and convenient if it were possible to duplicate a context via the Contexts view /manager/?a=context or at the individual Context view, e.g., /manager/?a=context/update&key=CONTEXTKEY.
This is a Feature Request and follows observed/expected behaviors below.
It is only possible to duplicate a Context via the Resource Tree by right clicking on the Context name to activate the context menu and select Duplicate Context. It is not possible to do elsewhere inside the Manager.
Retain the existing functionality to be able to duplicate a Context from the Resource Tree and:
Add the functionality to the Contexts view (by right clicking on the Context row to activate the context menu)
Add a duplicate button at the Save/Close/Help! buttons at the upper right. This would replicate the experience in Resource and Elements edit views.
