Actually previous versions of Affinity Photo did this. At least it did on my mac with versions 1.8 and earlier. When clicking on a particular panel icon (for example Brightness/Contrast) not only would the preset icons display, but the adjustment window would pop up. Apparently this has been removed in version 1.9, and now you have to click on the default icon to get the popup window. Perhaps there is a preference adjustment that I am overlooking. Sometimes I just want to simply edit the photo directly and not fuss with layers.
