Join app flaws

1) The JOIN mobile app is not having the Call Log option. From mobile app how can i access the call log of my another mobile with same login.
2) The chrome extension can be bit more intuitive. The below snapshot is from my chrome. It has at the top 3 menu's. I have two suggestions here.
           a) The SMS and Phone log should be separated for easy access
           b) When i choose a particular device from the list of devices and then go to SMS tab at top it should show the SMS from that device. But it is not. I need to click on the Send SMS from the 
               List of items below to do that. Its not intuitive.
