Sharing to Google+ from Google Chrome
I recently got an HTC EVO 4G LTE phone from Sprint. It has Ice Cream Sandwich, I believe (whatever 4.1.1 is). I downloaded Google Chrome and it came with a Google+ app. When I try to share from Chrome though, I don't see an option in the menu to share via G+. The Share menu contains "Bluetooth", "Dropbox", "Facebook" and "Friend Stream". I imagine the Dropbox option wasn't available until I installed the Dropbox app, so there must be some way for an app to insert itself into the Share menu. Clearly, G+ isn't doing that. G+ is a system app, so I couldn't delete/install it. I tried just uninstalling the updates, then brought it up-to-date again from the google market/play store. No luck. Any ideas?
