Hi Yves/Daniel,
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.

Cheers Pete
