This app is a must have. I wish it had the ability hotswap rulesets a bit quicker or at least name my exports... Can't import a rulesets that has had its name changed externally.. Also one time the entire app ceased to function blocking connections  I flushed rules and re applied but didn't do anything. Had to soft reboot to fix. Makes me a bit uneasy.. I'm having to check known blocked apps now to verify its working.
