Because it displays posts that i read already and scrolling trough several pages is a pain I know it's a small issue, but it would be cool if I had a choice.

Yes it does, but it got two options:
"View new posts" (like on talk.maemo.org)
and
"View unread posts"

First one shows new post in threads and second one shows unread post and if i read that posts they disappear form it.
It's really better It sounds the same, but it really, really isn't. I'm using this option several years on polish forums and it's more usable then the "new posts". Try it
I'm not trying to make a fuss Just saying.

Thanks for the links. Especially second one... wow how cool Online update.
