Anast, here some thoughts:
What will happen if a user tries to remove a track from a top crates, which is also member of a lower level child crate? Will both be removed? Can the user distinguish a track in a top crate from on that is recursively gapped form a child crate? We have discussed to use crates like tags. Do you like the idea ? Will there be something like a "crate membership" coloumn / search / sorting? How is a multi membership handled there? Kind regards, Daniel Am 31.03.2017 um 22:49 schrieb Be: > This looks better.
