Gadgetbridge Questions

Hi,

I have some questions for gadgetbridge.

1. It doesn't work with the mario-clock face. Any idea why? (https://github.com/espruino/BangleApps/tree/master/apps/marioclock)
   
2. I don't get calls, just sms/whatsapp/email. Is that not supported yet or what's the reason?
   
3. Why is connected in the gadgetbridge clock app toggleable? What does it do?
   
   

Would be nice if someone could answer those for me.
