It would be nice if an option was available to have a music sub "playlist" player that would play all the songs in succession in another tab, or even better a list to check off which songs to play from multiple subs. I have no idea if this is technologically possible or resource feasible, but would be great if you could have that soundtrack play while viewing posts, or doing other activities. Of course, some controls would be needed, such as pause, volume, repeat, skip to next (if no checklist option) to be really useful.
This might be better addressed as a 3rd-party add-on. Anyone want to take this on?
