Currently, Item functions allow you to create lists/groups which can be filtered down any number of times. However, it may not be possible to create the exact list of items that you require simply from filtering. Therefore, it would be useful if you could concatenate lists.
E.g. say you wanted a list of all items that were openable or were containers. You would need Objects.Openable and Objects.Container, so perhaps something like:
Concat(Objects.Openable, Objects.Container).List |
Concatenating lists
