Bumps...At first Gmail chat did not work in Chrome. The next day it started working. I did not install an update to Chrome, so i assume Google tweaked Gmail chat to work with it.
Things I like...
When one tab has a link in it that spawns another tab the tab opens right next to the tab that spawned it and not at the end of the list. Very help ful when you have several tabs open and when you are done with the spawned tab you want to go back to the parent tab.
Tabs run in their own process. This possibly makes it more stable, since one rogue tab most likely will not take the others down. It also allows you to kill a tab that is misbehaving without having to take them all down.
Tabs can be dragged out of the main app and made their own window. They can also be dragged from their own window into the main app with the other collection of tabs.
