sadly this great idea is implemented like crap even in goggles own apps.

open email, click a link which open in the browser, click a link which open in YouTube. now you have the email app activity in your recent app list, but if you switch to it you get a you tube video. now you either have the video/web page/etc, or the email message. not both. to get back to your email you have to press back all the way... it rarely creates such a clumsy situation, but every time it happens you're guaranteed to get very close to smashing the phone on the wall.

You eventually get used to it, I think of opening each app from intents like a stack and you press back to 'pop' the apps off the stack to get back to email (in your example).

Yep. And similar to seeing tabs in the switcher in L Preview, I expect we'll see a richer "switcher" that's more activity or history aware in some future release...
