I would love for there to be a way to balance or weight the shows in a Virtual Channel. For example, if I have 2 shows, one with many seasons and one with few, I may end up seeing way more of the show with few episodes (particularly if I choose the mini-marathon). I can see situations where other sorts may feature show with more episodes too. I found this feature in Tunarr as it's described:
Attempts to balance programming groups by either total lineup duration or number of unique programs. For instance, for a channel with many seasons of one show and few seasons of another, balancing will attempt to create an even mix of both shows by inserting repeats of the show with fewer episodes.
