Slide-in-up-animation for views on Android

Hello ionic team,

in the 800 nightly build there was a cool slide-in-up-animation for view transitions on Android. Why don’t you use it anymore in the actual builds? In my experience the actual slide-left-right animations are a bit laggy on Android. The slide-in-up animations on the other hand are smooth and lollypop-like. (testing on Nexus 5 Android Lollypop and KitKat 4.4.4) Is it possible to activate slide-in-up animations on the actual builds? Thx in advance!
