An auto-queue will be nessesary for many scenarios, such as if you wanna play a video but dont wanna skip whats currently playing. yes they could wait, but it would be more convienient.
Would also help revent intentional interruption, imagine this, you're like 50 mins into a 3 hour-ish film or somethin' and someone slides by and oh movie interrupted by amongus meme. that would be so annoying.
i hope the auto-queue option will be considered.
