Using Lawnchair and Nova I still cannot understand the fact that the animations (especially closing the app and going back to the homescreen) is still not as smooth as the default One UI.
Also I cannot find the option to hide apps on Lawnchair. With Nova I can set gestures to open an app and i think you can also hide apps there.
As I said my main problem with the default One UI is it is too cartoony & childish. Samsung has dumbed down the Theming option too much and there is no way to change the icon pack without installing a 3rd-party launcher. It's a viscious circle.
