Regarding the sticky list, i think it would be good to have solid lists that are complete and up to date regarding the three extensions available now.
It would be nice to have something like this:
DesignExtender:
-> Bug list
---> In progress
---> Fixed (revision#)
-> wish List
---> considered
---> accepted (next revision)
DataBridge:
-> Bug list
---> In progress
---> Fixed (revision#)
-> wish List
---> considered
---> accepted (next revision)
E-Cart:
-> Bug list
---> In progress
---> Fixed (revision#)
-> wish List
---> considered
---> accepted (next revision)
Then have some moderator keep track off all the posts bugs/wishes and update the lists. Then everyone can check what is posted and if it is already fixed (like Andrew mentioned) for the wish list you can mark the wishes you as support team think can and will be added in the (near) future.
Nothing works better for everyone if things are organised!
Above is just a structual example but you get the idea ;-)
