• We’ve already started working on increasing speed and response times for large libraries. We’ve heard this request loud and clear and we’ve made it a priority to improve things in 0.6.
• The MTP add-on for Windows will be extended to include sync functionality so you can more easily manage media on your portable devices.
• The iPod add-on will be migrated to our new device API. This will fix a bunch of bugs and allow us to maintain all of our device support in a single code base. It will also give us an opportunity to test the extensibility of the 0.5 device API and allow iPod support to benefit from features and UI improvements we roll into MTP support (and vice versa).
• Songbird will be adding the ability to write metadata changes back to your media files. This will include a new UI and will be our first time managing your data. We’re planning on adding Album artwork write back in a future release.

We’ll also be:

• Adding contextual menus and find functionality in the browser component of Songbird based on your requests.
• Cleaning up the View menu (so that switching Feathers, Views, and Display Panes is clearer).
• Continuing work on UI bugs to polish and improve the overall user experience.

While the goal is to land our MTP and iPod add-ons with the 0.6 release it is worth noting that due to the complexities and dependencies in these projects we might end up releasing them shortly after 0.6 launches. Everything else is scheduled to go out with the release. The current plan is to ship 0.6 final in the late May/early June timeframe. Until then, please continue to send us your feedback and file bugs as you find them.
