This is not a completely fleshed out idea, but I heard it a few times in different variations in online and offline feedback: It should be possible to save pages online and not just on the phone. It should be probably more like a bookmark than a completely saved page.
Some kind of identification will be needed for that. It can be a Wikipedia account, an OpenID, a Google ID, an Apple ID or maybe something else, so bug 37876 is a blocker of this one.
