In Vervis I have a property earlyItems, I think it's mentioned somewhere in the forum too. I just had a little idea about it and I want to document it before I forget.
The current setup: Given an ordered collection of X items, of which you wish to provide only the first A items and the last B items (A+B < X), orderedItems/items would be used for the last B items, and custom earlyItems property for the first A items.
The new idea: Use a "fake" paged collection that has only first and last, both mapping to OrderedCollectionPage objects. That's more cumbersome but removes the need for a custom earlyItems property.
That's all, I'll examine this idea when I review the open issues/topics about earlyItems :)
