I can understand not wanting to reveal company secrets, but it seems it would be simple enough to have the internally proposed upgrades, and only post those ideas submitted by the users/general public. It would seem to be far easier to scroll down a list of suggestions and see the status of each, rather than having to search the board, open and read each topic as well as many/all of the replies.
I suppose it's not that important, I was just looking for a way to keep from posting the same suggestions time and again, because I either forgot they were already suggested, or didn't use the same terms for the suggestion that were used in the previous posts.
