Extension does what it says and works well, but only gets 4 stars because the smallest delay you can adjust is 100ms, which is a HUGE delay... So it can often be impossible to get things synced perfectly.
Author should really add a field to manually type in an offset value, or add 10ms increment buttons as well.
Thanks for the feedback! You're right, 100ms steps are too big. In the next version I'll add manual input — click on the value and type any number from 0 to 5000. Thanks for the suggestion!
