hi Oliver,
a suggestion i know from another script I use how to sort content parts.
There is an additional field where i can type a number and be able to do a fast sorting of content parts within an article.
I use this in a news page and if I add a new one it goes to the last entry and i have to click severals time to get it on top.
I know i can set in structure level another kind of sorting :-) but when i select date of creation and edit it later the sorting isn't still correct.
I have a screenshot of the backend of photokorn ->http://www.telekorn.de

ADDED:
Or would it be easier to integrate the copy-paste function as in articles and structures to duplicate content types?
like this:
