There is one option we have been asking for so long. We request that you add an automatic repeat option for each subititle. Lets there is an important sentence that I don't understand the Language Reactor should repeat it for as long as I fully understand the sentence while I am taking notes so I dont have to press button for current subtitle each and every time. We have been patient and did not leave so far so please add this option as urgent. It critically needed.
