Would it be possible to show a list of all item on the wishlist for each extension you do? And also have a voting system for each item to help build the road map? Sure a couple of programmers like you two could sort this out in your sleep! Seriously though, really think this kind of feature works and helps people on many fronts. Existing customers see where it is going and feel they have a voice to get in features they need. And new customers can see they can get involved and the extension has a development plan.
