Huge Update to Google Search
Google Search 18.104.22.168 is rolling out now, and it brings some awesome features. You can see some of them here.
Some things not mentioned (that I just found out):
- Opening an app by voice command is now infinitely faster.
- Update brings conversation mode (try saying "send text").
- Ok, Google now works from any homescreen on my Nexus 4 (I don't know whether it works on all 4.1 devices with the new update)
