I also suggested a voting/tracking system for feature requests but received a no from A&H a few months back. Best option at present is one suggestion per thread so users can do the +1 replies..
Note to A&H: when you setup the feature requests system, allow each user to prioritize between suggested features. Each user might be allowed maximum number of up votes, or they might be able to sort from most desired to least. More meaningful than just +1’ing suggestions that tickle their fancies..!
