I love having most used contacts on there. One tap and I can call or text without opening up the phone. I also use Capture + a lot and my five favorite apps.
I have 3 pages
1st Page. Music player controls
2nd Page. Quick Toggles ..Sound+Wifi+Flashlight+Bluetooth+Camera
3rd Page.App Shortcuts.. Calculator+SureRemote+Gallery+QuickMemo+Settings ...
It's a very useful feature that I use every single day....Starting to think I may get a little too used to the 2nd screen and IR blaster to go back to the Note Next year.....
I haven't really customized much, just been using it to toggle basic controls and some switch apps. And when my ocd kicks in and I don't want to see it- I have the signature blank so it comes up as a blank screen. Then with one foul swipe I'm right back to what I need when I need it
I have the quick tools, signature, recent apps, app shortcuts, and music player when the main screen is on. I mostly keep it on the quick tools unless I'm playing an audio service. I didn't have the V10, so it's taking some getting use to.
