Just some suggestions I hope you can implement if possible

Android (and Android TV)
1. With the built in mezzmo media player add support for left and right arrows on the remote to rewind/skip 5/10 seconds (without bringing up the seek bar) , most media players support this and it's really the only reason I have to use a 3rd party player.
2. On the Android TV interface would it be possible to have a option force vertical scrolling vs horizontal

PC
1. there is no way to sort/find what items are locked (no customizable coloume for this) , so I have to go through each item to find what ones I locked from editing, which takes forever and often will crash mezzmo if I edit too many at once.
