I know it's a small thing, but needing to log in with the email and password every time I want to hop on for a game is mildly annoying. Saved login info would be a tiny fix that would save a bunch of aggrovation after a game crash too.
I thought we had this in ages ago, but apparently it was commented out ... weird. Anyway, we'll save your e-mail, but not your password. Though it will get wiped every time we update the web build.
