The introduction of the merge top containers function in 2.8.0 is a great help. Unfortunately, it doesn't scale well to collections with many duplicates.
Each time I merge top containers, I am taken from the manage top containers view into the surviving top container record. In order to continue, I have to:
Go back to manage top containers
Start typing the resource name in the resources field
Select the resource
Wait for search to complete
Sort by indicator
Go back down to the next set of duplicates
I would expect (and greatly prefer) to be returned to the manage top containers view after I merge the top containers, which is how all other bulk operations work.
