For some time now, projo has been offering the function to merge two performance states (yes, that is the plural of status;)).

projo also provides information about how often the respective status is used in your PROJO account.

In the past, before deleting a status, projo informed you which projects it was being used in. We would think it would be right if this functionality were restored and even when two states were merged, it would be visible in which projects they are used.
