Please, please, please give us an option to disable calling in the mobile app. It is so annoying that this is not a feature. People always have their phone on them, but if I am doing something important while my friends want to play video games, I should be able to turn calling off in the mobile app only. I still want to be able to have full functionality in the desktop app, but not receive calls from my group when I'm at work or out having dinner/drinks with the boss(or ever on my phone really). To sum it up... Allow us to have full functionality on the desktop app, while giving us the option to disable voice/video calls in the mobile app only while retaining text chatting.
