    Help. When using colours-components-decompose/open value then use unsharp mask, I cannot enlarge the preview box to see the effects of sharpening. Any-one know how to overcome this.

    You have to pan around. With some habit you know where to look for side effects. One reason for the small preview is that unsharp-mask involves some rather heavy computation, and on a small computer a large preview would not be computable in real time. But I agree this gets a bit historical.

    I've seen a brilliant concept a few years ago about a glassy-look Gimp. In included a preview window that was resizable and draggable, which to me looks like the best solution. But I can't find the image at the moment.
    Here is a similar image describing what I mean:

    I have no solution here, unless you want a 200-pages manual with instructions telling you how to build your own Gimp "fork" :)

    You are right, I need to stick with it. To be honest I missed a trick, after decompose I only view and adjust "value". Getting some great effects. Thanks**
