Agreed....that would make my head hurt.
You can limited it to just one command per zone or even just one side zone; completely user friendly*.
Very versatile.
Make it as simple or complex as you wish...
Perfect for a curved screen phone; use that lost real estate... you can adjust the position/length of the zones as well as how wide they extent outward from the side. Nearly seamless integration.
I give this app 5 stars... play with it.
*lol, I use PowerAmp too and got that tamed, this isn't nearly as complex, pretty intuitive but you need to explore it fully to realize it's potential. I'm still dialing it in after a couple months, I tweak it bit and use it for a while, or if I don't like the tweak I change it.
I use it to turn off the screen and power off too. Literally have 3 different ways to turn off this device. Have Double Tap running too. No conflicts.
