Before the community existed in this form, Sonos had a website where feature requests had a separate status, and could be voted for. Some features introduced back then were based on popular demand. Now, requests are scattered across the community and receive the same (non-)reply every time. I think it would be good to have a separate place on these boards for feature requests, just like the "Ask a question" board. Adding a "me too" button or using the original "like" button, votes could be cast for a feature request.
It wouldn't necessarily change Sonos' policy on giving information on the status of development - the previous version of this system even had a "under consideration" and "rejected" status tag - but it would at least give some visibility to highly requested features.
