I just edited my post above, but for those of you that already read it and won't go back and the others that just don't go back to read, I'm double posting here some ideas on how to use the gestures on Nova.
Hints : Use swipe action in folders to open apps, plus use the swipe down gesture to Expand Notifications, this helps a lot for a one hand use, plus I use swipe up for Google App, so I can get rid of the widget using precious space. Also, Double Tap I use it to open Camera, I know we have Double Home Tap, but common sense tells me that the more we use the Home button the faster it can get damaged, so if I can prevent that with the same action, Double tap, but in the screen instead, I think it's better in the long run.
