If topic multiple pages, rollover navpages hide/show div

[samborabora]

Okay, I said that the last time I didn't want to reference KTT, but there's one more javascript coding thingie I'd like to work out. http://www.kanyetothe.com/forum/index.php?board=1.0 if you direct your attention to topics with multiple pages, the topic starter text gets replaced when rolled-over by the navpages function, the multiple page selection navigation. It's just a nice, compact way to display the pages without needing it at the same time as the OP info. Is it difficult to add, or would it just need a little javascript? Presumably some PHP would be needed to define if the topic had multiple pages or not?
