Collection Manager

Thank you for the review and suggestion. Can I ask you more about "making use of nested collections"? Is that something in addition to being able to assign the same number to multiple collections? Do you mean something like assigning a number to a collection would also trigger all of its sub-collections?

Perhaps it would be better to open an issue for this feature for further discussion, rather than trying to discuss stuff here.

Note: I can't promise any kind of time frame for this right now, but multi collection slots is something that I have tentatively planned to explore at some point.
