Touch control would be very nice and comfortable for tablets or phones to adjust volume and seek in movies.
Analogous to Synology DS Video:
Move one finger vertically (up or down) on the playing movie to adjust volume
Move one finger horizontally (left or right) on the playing movie for seeking
This is a really cool feature, everyone knows that who ever used Synology DS Video on iPad. I really miss that from the Plex client app.
