I'm not sure whether it has been improved in 1.0.0 or not. But as I see in 0.6.0RC3, I found that it's hard to inject something dependent on resource. For example, if I want to create an object definition for GUI, I need to be able to link "Image" object to an image/bitmap in .resx file. It seems to be fairly difficult to do. I wish to see either some additional support for this. If there is already such support, it should be documented in the manual.
