I may be missing it, but is there a section on the website that lists what features you're working to implement?
If n ot, it'd be a good idea. I picture it having at least 2 parts. The first is a list of the current features or fixes in development. The second would be a static list of development priorities (i.e. bugfixes, interface adjustments, new features, support for additional encoding format, etc.. You could also include the status of each feature (planning, development, testing, etc.), and/or a list of features that have been recently finished but not released, or just released in the latest version (to prevent 'what happened to feature x?' questions).
