It's only possible to log the last call I've sent/received. This is an issue for me because I will frequently have back to back calls, upwards of 5 calls in 10-20 minutes. I do not have time in between the calls to go into my notifications and hit the log button. I am suggesting adding in a call history section that will allow me to go and see all the calls that have taken place in the previous ~24 hours, or longer. This will allow me to have as many calls as I need to and once I have a free minute I can go back through and log all the calls I've had. As it stand I am missing out on a lot of activity when it comes to calls.
