I loaded up the new Mailroom app update and noticed a major change in the way the address bar was displayed. Initially, I had thought this to be a change native to the app, but it’s apparently a change to Gmail itself (tested in Safari).
You can now add frequently (or recently?) mailed contacts to a message by simply tapping on the + button on the right side. This change is relatively minor, but it’s another step in Gmail’s journey to becoming a web app that feels like it’s native. I’ve basically lost all hope for a truly native Gmail client from Google on the iPhone, but if improvements like these keep rolling out, that might not be such a bad thing.
I first suspected this to be another undocumented change, but it looks like we have the iPad to thank for this address bar revision (see the screenshots).
