The whole UI is meant to slide/pan from right to left as you "zoom" into a property. This won't be so helpful, but let me say it anyhow: Is there another way that you can re-frame the problem? The problem here is building a query where a constraint might be not on an immediate property but a property several hops away. You're using pivoting to get "there"--to get over several hops. I've tried to use "group by" to achieve the same effect to some extent. Maybe there are other ways. >> This is actually a very subtle point >> > It is, but it's a good one.
