Multiplex Sources performance

The current behaviour of Multiplex Sources node plays all video children nodes even though they are not active. If I have a lot of Video Loaders under a Multiplex Sources node the performance will be affected dramatically. May I suggest an option to just play the active video?

Another scenario is when I want to play multiple videos one by one but it has to play from the beginning of the video when it’s its turn. Currently I have to retrigger all Video Loaders (via Retrigger attribute) every time the index changes. Again, this affects the performance and makes the nodegraph more complicated. Please consider a feature to handle this.

Thank you,
