I worked at a BiqQuery shop and they have a terrific feature where right next to the “Run query” button there is an estimate of the cost of the query, in bytes. It becomes extremely obvious when a query is a full table scan.

Ha! I wonder if we worked at the same place ... it's in the travel space, because when I worked there someone wrote a plugin that did this, and it was a real eye opener at times!

Nope, not travel! For us it was a built in feature, not a plugin. This was earlier this year also.
