Currently, I have Google Chrome 33.0.1750 installed on Ubuntu 13.10. I noticed, recently, that when I open a new tab the applications view was replaced by a google search widget and recent tabs listing. I didn’t launch apps frequently, so it was no big deal for me until I tried to open a tab that I had opened previously on my android phone. The button tabs from other devices was also removed (well just moved).
To acces tabs from other devices you have two options: launch it from menu->recent tabs (which didn’t work for me, it appeared blank) or press CTRL+H to show history and you’ll see at the top, the list of your devices and open tabs.
It seems a lot of people doesn’t like this change, me either.
