In My job I have to be both dev and designer ... I am not as much a Gfx designer, more code side.

I want to do better at design and Gfx.
I am always looking for more on how to do it better.

I'd Love to see some stuff on how to approach using Expression studio to build UI for an app.
I'd also love to see more tools for pulling apart .psd files to use in SIlverlight and WPF
some kind of converter from .PSD to Expression design format.
not just a bitmap, the layers, effects etc...

UI and UX are for sure very important 8? 9? as long as the rest do not have to suffer... function and code quality can not be left in the gutter.
