I'd say the answer is no. Why? The primary function of the preview is to preview the effects of certain parameters on the image. It seems only logical that the preview updates as soon as possible after a parameter change. When the plug-in algorithm is fast enough, I see no reason why the preview should not be updated automatically. The only alternative that I see is to have some separate "Update preview" button, but that is just awkward for the user. Ernst Lippe
