Thanks for the reply. My post was focused on Studio because there is a way to see all indexes for a table, but it's missing the index number. Studio is a pretty big product, and it may be that I just couldn't find it in Studio. If it's not there, I think it should be added to the index information screen.
With the Administrator perspective, some of the items from the Object Viewer are still being implemented. Showing the details for an Index (such as the Index Number) was one of them. We hope to have this resolved in our next release.
