The "RC" (remote control) button on the app handles this perfectly, and would be great to have in-browser as well. Having to go to Settings > Players > Select Player > Select New Mode > Save is a lot of steps. Plus I usually have multiple listings of my username under Players, i.e. Player 9 [username], Player 10 [username], Player 13 [username] (because of DHCP assignments from router I assume? Or logins from other devices?) so it usually takes a few tries to figure out which of my logins shown is the one that I'm currently using, and need to change.
thanks Sindre!!
