Since it's a bit hard to keep track of ideas in the forums, we're now using
UserVoice to record user suggestions. You can access it via the "feedback" link attached to the right of the window. The direct address is:

We're using this mainly as an organizational tool, but it'll certainly be a big help if you vote for suggestions you like so we can prioritize popular ones. It's really easy to use and you don't even have to register an account. I've populated it with pending feature requests, but if I've missed out on any suggestions you're more than welcome to add it to the list.
