Would you like to keep this list on Head-fi or would you like to start a list on a dedicated bug/feature tracking platform?
Personally i think that to enumerate the list at all just head-fi is fine, but to do anything else like prioritize, head-fi will not be sufficient.
I suggest we start here. This could still be changed if more and more bugs turn up. But you have people from all over the world here, head-fi is THE (now I did it like you ) one place for people to stop by for all things FiiO.
