iPhone X Navigation idea

Not the best visually, I admit.

So I am having a really hard time conveying this in just one image, but as soon I saw the new way you could scroll through the bar at the bottom on the new iPhone X. I thought what if the bar was colored or gradient based on all the "open" apps you currently have in multitask.

So you could swipe through the colors at the bar OR force touch and scroll mode in a more multitask UI.

I am going to try and animate this a bit but wanted to share here.
