XF 1.5 Preview on "New posts" list: Possible to preview first unread?

[johon]

Is it possible to configure either the preview of the posts that are shown under "New posts" in a way that not the first post in the thread is shown by the preview but the first unread post or that in the list of new posts the first x characters of the first unread post are displayed in the list?

This would require custom development.

Hmm, that's bad - but thanks for the quick reply.
