Better brush management with brush set previews.
Improved integration of Typekit
I guess I'll add a me too foe fonts by family, although I don't generally hunt for fonts.
More noise and texture generators of the Clouds and Fibers variety.
Someone is getting very good with the Render options. I've used trees several times, one of which is currently being used as the banner for the PSNZ Facebook group (but it's been up for a few weeks now and must be due for a change soon). It is also an old version of which THIS is the finished image. The render fire script is excellent. Much better than the Alien Skin Eye Candy 7 fire. So more of those would be welcome.
The defaze demo we've seen is also impressive, and something that would be genuinely useful.
How about more visible guides and paths for the very high dpi people? Not something I have problems with, but we do see a few folk mither about it.
More align layers options. It feels wrong that we need to rely on Chucks panel to do equal space between layers, (although I am grateful for the panel Chuck).
Speaking of equal spaces, I miss the Trevor Morris Dmonzon tools panel, (he shows no sign of getting to grips with HTML5) and would love to have some of those features built in.
