The biggest improvements/changes include enhanced priority inbox support, an improved compose email feature, and in-line rely responses. With priority inbox support, users can now see importance markers in the main message list and rank messages right from their device. That is if you actually use priority inbox.
The new compose feature will allows users to switch between reply, reply all, and forward while in the compose screen as well as set the outgoing account on the fly if they have more than one Gmail account on their devices. In-line message replies work similarly to how they work in the traditional Gmail interface.
The new Gmail application, which carries the designation of version 2.3.2, is available in the Android Market now. So far the update seems to be working fine on our test HTC Incredible. We’ll let you know if something breaks.
