I already posted on the suggestion threads marking them as implemented, but to summarise:
There is now a filter for free/paid resources: http://xenforo.com/community/resources/?type=paid
The resource post content is available when hovering over the title.
Ratings and reviews can now be given via both sets of stars.
Two thumbs up to Kier and Mike for this latest update...also, thanks very much for allowing us to post paid resources here at xf.com, it is very much appreciated!
I didn't follow discussions about the Resources manager. All I know and all I see, that it is really great and very easy to use. A big "Thank" to the Xen Team.
