Works great misses importent core features. I'm still missing a tool that let me adjust the audio by frames, fyi Marques Brownlee did an experiment uploading and downloading the same youtube video 100 times and with every upload the audio will shift 4 frames. And one thing that annoyed me today, was that a video had switched stereo channels, would be great to have a checkbox aside Mono that says switch right and left channel. Then this tool will be a five star add-on for me.
