1. Split screen functionality is dealbreaker for me - right now interrupts first app sound until you select the second one.
In Huawei is realized very elegantly - if you hold Back buton or hold back gesture for a second, it pops a side bar with apps to select (this bar have ā+ā buton to add apps to it, this allows you to start app that is not already started). And first app sound keep going on.
Also there is no feature to change the places of the apps in split screen mode.
2. Please, please let us edit the Gmail widget - or just remove New mail and Archieve butons that waste so much space.
