Thanks for your review @Oonix. Unfortunately at this time there isn't really a way to shorten mute times because the filter doesn't have access to precise enough timing information. Most of the time it only knows when the captions get added to the screen, not how long they'll be there, or when each word is said. I will be working on adding an algorithm to try and reduce muting time (with a possible decrease in muting effectiveness) in situations where the filter does have start and end times for a phrase, but I'm hoping it will be about 50% shorter on the mute times in a phrase.
