Some things planned for the future are keyword based lookups of Technorati feeds (that meet very specific criteria to ensure quality content), auto-cron setup, and social media support (ie del.icio.us API notifications etc).

If you would like to see support built into a bundle, or have a specific need for a niche bundle, heres where you can talk about it.

Publishers of new plugins are also invited to comment here - who knows, your latest may be just what we need :)
