It has been two weeks since Android 4.0.3 started rolling out to the Transformer Prime, which made it the first tablet to officially receive the update. With a new version of Android, be it incremental or not, comes new and improved GApps, most of which we've already taken a close look at.
In Android 4.0.3, however, a new Gmail feature has been uncovered by ComputerWorld that is noticeably missing in its 4.0.2 brother: experiments. Sounds dangerous, no?
As you can see, these "experiments" is really just a couple of useful options that someone at Google probably deemed "worth including, but not entirely stable."
The first option, Enter full text search, is pretty self explanatory - it indexes full messages, which allows you to search through all of the text for keywords; a useful feature indeed.
