We have a lot of things planned! But the 0.4 update is planned to be Corruption and Dialogue focused. Basically buffing out her dialogue abilities (She can now have convo's with NPCs, She randomly speaks to you at times now, and a few other small things). The Corruption system is also a way for the players to change how she acts a bit and might even display a few new animations.
Plus I've reworked the Gallery to display items, animations and popup's after they have been discovered! Of course there is a command to unlock all of them if you wish to skip that process.
