Hi,
I use the connection screen (show active connections) a lot and I think that it will be easier if the total speed are show in the program, so I don’t need to search the connections one by one.
Sorry the english. 
FYI This is shown in Killswitch - Click on Watch activity and it will download. then navigate to the cconnections tab.
CIS is personal security software and total bandwidth usage is not usually a personal security issue so it’s shown in an add-on not directly
Think that is right but if you disagree, please do say why.
Best wishes
Mike
