When you do a `Where Used` on an item, the query for the first tab `Used In` is automatically triggered. As we all know this is a very expensive operation with potentially hundreds/thousands of resulting items. This makes no sense in my opinion, especially if I'm not interested in the results of `Used in` and I just want to get to the `Uses` or `Published to` tab. The same behavior can be observed when switching between the 3 tabs, clicking a tab triggers the loading of the items/data. My suggestion would be to change the `Refresh` button to `Load` (or some other meaningful name), and load the items only when explicitly requested, similarly to the publishing queue's (PQ) `Show Tasks` or refresh icon. In the PQ you only get results when you ask for them, of course it's because there's a lot of filtering options, so it's somewhat different, but I believe the mechanism should be on-demand in both areas.
