it would be amazing to have "lists" among the field options to Content-Type.

Currently each field can hold only a single data point. With lists we could have multiple data input. So far the only way to do something similar is to create new Collection (which would work as a list) and related it to another Collection. Ex.:I want the list all people that liked a user. I can do it only by creating a collection for the likes and relate it to the specific user.

Instead if we had "lists" as fields of a content-type (like most DBs do) it would be much more efficient
