A few minutes ago I realized my iOS 9 wish list has grown to 3 items.

• f.lux functionality built-in to the operating system. It makes my computers so very nice to use.
• PGP key support in mail and the OS. S/Mime is great but support isn't everywhere and it would be nice to have both
• Notification sets. Being able to group a set of notification preferences. Do not disturb is handy but it's the nuclear option. Sometimes, or everyday, I would like to have different "work-day" and "off-hours" notification settings. As a bonus for my colleagues this would man my phone could buzz a lot less while we are on conference calls.
