I love slide #4 :)

Here's an alternative to presenting the query path:

Properties that have deep constraints appear like "finger tabs". 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.

Not sure if I understand...

Oh, you mean the yellow synchronized highlighting...

We can carry on this conversation off the list.
