I was just about to post a similar suggestion too.
I would like the ability from within the Admin CP > Node Tree to be able to quickly edit the display order of the forums, and then click save underneath. Maybe a text box next to each node with the value in?
Even better (technical problems aside...just thinking outside the box) would be a draggably sortable list.
Is there any mod that makes it so forums are defaulted into being sorted in alphabetical order? I actually really need this, now that I think about it.
I made this thread in Jan, I still don't know if it applies with the advent of 1.1, perhaps Brogan can dig around in the admin CP and have a check for us?
