I think that people are feeling a bit constrained by the structure of X collections and X videos.
If we could buy X videos (in my case, I would be buying a full stack of 10,000, and then put into whatever collections we want until we use them up, that would be ideal.
Because I might have a collection with 10 videos. And I might have one that could use 135.
As long as the videos are counted, that would allow you to plan better, and us to get the flexibility we need.
