Games bring 5 times more money than apps. Please stop ignoring this industry.
Where is 9 slice scaling for bitmap assets and smartobjects?
Where is assets management (sprites, atlases)
Please keep in mind that this isn't a full release at this stage. It's a 'Preview'. There is plenty of goodness coming before it is an official release.
I'm currently using fireworks for game UI design as it's the only tool I see in Adobe's suite that supports 9 slice. I would love a tool focused on game interface design and layout including sprite sheet packing and optimization! Here's to hoping XD can lend that support in coming builds!
