[Roscoe]

Once the "toolboxes" are on screen there's no way to minimise, maximise or close them. Not even drag handles to make them smaller/larger. They take up too much real estate, making it harder to see the image on which they're working. The only way to get rid of them is to finalise the adjustment process, saving the image. Once saved, no further adjustments can be made, unless the whole process is re-started with the modified image processed again.
