An alternative to syntax highlighting might be query structuring/beautifying (on command, not by default).

And +1 from me for search history. Thanks for building these apps. Sequel Pro nails it for MySQL, but up until lately there seemed to be a void on the PG side. I've been using PG Commander for about 5 months and am excited I can use my license on Postico. So far the app works as I expect it to, and looks fantastic.
