I'm in the process of moving off a certain Russian AV product for obvious reasons. As I go through setting up BD on all my family computers, I'm finding a number of operations awkward. But there's one thing that multiplies the annoyance: I have to individually configure the settings on each computer, over and over.
So my suggestion is a simple means to save all my settings from a single machine - all the firewall rules, various protection settings, and so forth. Then I could just bring that file to the other machines, load it up, and I'd be done. Or even better, don't make me write it to a file: just let me manage it from BD Central, give me an option to copy settings from device X to device Y.
Observing how you love to keep reminding me to add more devices to my account, I daresay you'd be more successful getting people to add devices if you could make it this simple to do so.
