Great, this is a very nice addition :)
A follow up suggestion is fine-trimming in the android app, if this isn't already going to be a feature in the new app ;)
What I mean is;
for example dragging the finger upwards from the seek bar reduces the amount it moves forward - kind of like on iOS movies. This way you have more precision seeking on mobile, as jumping 1 minute in a long movie is very challenging hah ^^
