I specifically don't want a unified inbox. For that you can simply use the regular iOS mail app. What I use gmail for is accounts that I want to keep separate, for consulting business and not get that intertwined with my personal email. What you see as a shortcoming is for me a feature.

someone always complains, but really, this is a great app. Google had a bit of a shake start with their gmail app, but now the suite of google apps, Drive, Gmail, Search, Voice Search, Goggles, YouTube, Chrome etc are all world-class. When Google Maps comes out I am sure that will be too.
