Adding functionality to the Edge - Which apps and/or Custom ROMs to use?

My S6 Edge will be delivered in the next couple days and I'm gathering some info on how to get the most functionality out of the Edge. When looking at the Note Edge, the larger edge allowed a great deal of native functionality, like the swipe out app shortcuts, and swiping down for a widget bar with wifi/flashlight/etc toggles. I'm looking to have the same or greater functionality on the S6 Edge.

Here's a couple apps I've found that look to work well with the S6 Edge:

for app shortcuts, you add this as a feed: QuickLaunch: http://forum.xda-developers.com/gala...-edge-t3090255
for app/widget shortcuts, usable anywhere without the toggle bar: SwipePad: https://play.google.com/store/apps/d...ipepad.android

Anything else recommended as a favorite addon app for functionality?

I also plan on rooting immediately. Is there any recommendation for a Custom ROM that may have additional options along these lines? Or just, in general, any recommended ROMs I should consider installing right away?

Thanks guys!
