Thanks for your feedback!

Please keep in mind that the lifespan of Kunena has been about 2 months. During that time, we first concentrated in giving Fireboard users a stable forum while laying the foundation for fast Joomla 1.6 development and native Joomla 1.5 support. Kunena 1.5.x is nearly finished and some of the things you've requested were planned for the 1.1 version; but we've skipped them to concentrate in Joomla 1.5 development. These items will be added later, including SEF/SEO, impressive performance tweaks (way more than the ones already achieved and currently in testing on dev team personal sites). On a side note, query count is not a real indicator of performance. But we'll have new APIs for third-party plugin development and template customization.

Obviously, we try to listen to our users as mush as we can. We even have a site where you can post your opinions, suggestions, and areas of concern at kunena.uservoice.com. Give us your feedback!
