As is usually the case, a major update to one of Google's applications brings out a new version of what's popularly known as "Gapps or Gbits" -- a collection of all of Google's closed source applications for Android. Updating the voice search application to include voice actions brings them out this time, and some changes to the Gmail app along with.
As you can see above, the message headers are smaller and bunched at the top of the window, and it really does make a difference if you like to mark messages with a star for later action. Other changes are a new reply button, which opens a small bubble with reply options (meaning you don't have to scroll all the way through a long message to reply or forward), and the choice of whether to include quoted text with a reply. Screen shots of both these are after the break. These are now included by default in CyanogenMod, expect to see it in other Froyo custom ROMS soon. Sorry, these changes are Froyo only. Don't shoot the messenger! Holler out if you have found any of the "Lots more cool stuff" we haven't seen yet.
