Interested to know how you were gonna fill up that Chrome OS app page? Google just announced its new online web app store at I/O. So far they've shown off Dark Room for image editing, a pretty slick version of TweetDeck, and yes, like every other platform known to man, there's Plants. vs. Zombies and Lego Star Wars. For-pay software will be offered -- Dark Room is $4.99, if you want to go ahead and put that money aside. No word on a launch date, but we'll keep pushing for more.Google unveils Chrome web app store originally appeared on Engadget on Wed, 19 May 201
