mhaze, while that could be nice for the Power Fractal specifically, I don't think it is generally a good solution. That would mean we'd have to have a uniquely placed shader preview area in each shader node's settings. UI design best practices would suggest finding a more general solution, which the previous behavior did have. It was thought that it might be better to reserve that shader preview for shaders selected in the Node List, but that seems to be less intuitive and useful than the previous behavior judging by the comments here. We'll work out a better approach for the next update.
Thanks for the feedback everyone.
