I hope you can also make changes to the wallpaper because it can only be applied to the home screen but when you pull the app tray it only displays white. I wish we could customize it a bit. In addition to that, for some odd reasons I don't like how recent apps are being shown on the very top portion on the app tray. Somehow, it makes me feel uncomfortable most especially I am using a dating app which should be kept in private. Also, there's no option to hide/unhide apps plus the apps are arranged alphabetically which is a little annoying.
Anyway, these are my observations and I hope these can be addressed in the near future
