These are cool, but I wish someone released a library with pixelshader effects more designed for UI elements. Most of these effects wouldn't be routinely used in UI design. For starters, I'd like a good replacement for the Outerglow bitmap effect, and I'd also like a few other types of glow effects, like those mimicking the ones you see on the taskbar. Im sure there are others I could think of also. I don't know how to do HLSL yet myself.
