Hi Simon, thanks for posting this feature request. Extending playlist support to web isn’t on our current roadmap. Primarily that’s due to differences we see in the nature of watching on mobile, compared to big screen devices, where our web player is used. On mobile we see regular use cases for viewers watching shorter clips - and those can be in a playlist - whereas on web we see more focus on longer form content and live events. As such, the playlist feature has helped to improve mobile viewer experiences with the seamless transitions you mention, however, on web we are putting greater emphasis on high quality, performant playback on big screen devices, with a particular focus currently on SSAI streams.
We’ll certainly keep an eye on your feature request here and whether this is of interest to our other community members (please post or vote if so). Additionally, we’ll be making some framework updates to our web player later this year and this may open up new possibilities so please stay tuned for more on that topic in the coming months, or in the meantime check out our latest blog: Developing a Video Player with Structured Concurrency
