Ok tried the pixel launcher and the new gestures again. Pixel launcher is ok, but I like my customizable gestures in Nova and my custom icon pack better. Can I use it, yeah but I don't have to so I'm not going to.
As for the A10 gesture system, it's ok, I can use it, it took me a couple days to acclimate bit I still don't see the point. The buttons are faster, and the work with all apps. Some of my apps and games use similar swiping gestures so I end up doing something I don't want to often. Recent apps is slower to and honestly I don't go very far into the recent apps list, never have really so it's not a huge deal and easier to just double tap the square button for quick switching easier.
Just my opinion but I don't see the allure of the swiping. It works and o can use it but I don't see how it's better.
