1. 2. Please please get it working on iPhones!
Two more possible improvements.
I'm at campaign level, looking through my ad groups.
I choose one I want to examine, go to the ad group level. Look at the ads.
Now I want to go back one level to look at the ad groups again. I can't. When I go up it stays in the "Ads" tab and shows all the ads in the whole campaign. I have to click again to see all the ad groups. Might seem like nothing, but with the slow loading the seconds add up.
