- Unified design! No more cheap leather or stitching, it looks so tacky.
- Redesigned App Store and iTunes, I actually preferred the old ones.
- Better file management, particularly in the Photo app.
- Scrollable folders, quite annoying to have 4 folders called "Games".
- Redesigned music player, again I preferred the old one.
- Improved multitasking
- Ability to display notifications in the lock screen! If I have a reminder coming up, it would be nice to see it by hitting the power button. Currently, one has to unlock the phone and open NC just to see a reminder, not exactly ideal is it.
- Some more life into the OS, it looks a little static as it is. Maybe something animated in the lock screen to liven things up a little. Live icons could also be good, with the ability to disable them of course.
- Ability to set different "Do Not Disturb" times for different days. This is a glaring omission.
- A more attractive Notification Bar, that grey thing isn't very pleasant to look at it. Perhaps a more fluid animation also, the way it drops down is quite boring.
- MUCH MORE capable Notes app. The current one is pathetic. It should be much more functional with bullet points, photos, attachments etc. Also, make the paper white or at least give is an option. I dislike that yellow paper!
- A quicker way to switch Wi-Fi on and off.
- Ability to remove certain built in Apps. I HATE newsstand.
Finally.. just a general aesthetic redesign as the theme is becoming tired. It should be made a little more elegant, perhaps the use of Helvetica Neue would improve things. I'm sure Jony Ive has some ideas.
