Comment 135 for bug 332945

Jamin, to address your three points once more: (1) Yes, it is more obtrusive, that's entirely deliberate, and I don't know what "study" you're referring to. (2) Using a notification icon to advertise updates is a bad idea first because it's not obvious, and second because it makes installing the updates gratuitously difficult. (3) Using a notification icon to advertise that a restart is required is a bad idea first because it's not obvious, and second because it makes restarting gratuitously difficult.

Peter, yes, <https://wiki.ubuntu.com/NotificationDesignGuidelines/Comments> would be a better place. You'd need to include how the persistent notification would ever be dismissed, and (if it would be dismissed by clicking) how you'd avoid mis-clicking on an unexpected bubble.

mac_v, you have a good point that we could improve performance by checking for non-security updates either a week after the last updates or whenever security updates are available, whichever is earlier, rather than checking every day like we do for security updates. I've added that idea to <https://wiki.ubuntu.com/AppCenter>, thanks.

ktp420, yes, you'll be reminded again a day later for security updates, or a week later for non-security updates.
