At the moment, when the "Transparency" option in the "Display Quality" of the workspace is checked, only hte opacity of vectors is previewed, not images. I'd love the option to be able to preview images too with actual opacity, without having to render.
I know it will slow things down, but processors are pretty fast now.

not only can't you make images transparent, you can't make groups or bone layers transparent (well, you can, but you can't see it in work-view).
This is a big pain seeing as how most characters are made up of many layers, and the ablility to see your character with transparency is fairly essential...
