Preset marking

Hey, just a little thing I find lacking.

When you double click a preset, you have that blue outline around it, and it's rendered in the main window, but if you click on any different preset, the outline goes to that preset, even though the render is still for the double clicked preset.

What makes it worse, is if you go to another filter, and then come back to the original filter. Then you have the double clicked preset rendered, but the outline is on the default preset.

I find it very confusing, and would live to see maybe a red+blue outlines, one that shows which preset is being rendered, and the other shows which preset has been selected with a single click. Obviously, if the user changes the settings of the preset, the red outline would disapear.

Different kinds of colour-blindness mean that UI guideline is not to rely on different colours to distinguish these kinds of states.

I'd prefer a small badge to indicate the currently rendered preset and an outline of whatever colour to indicate selection.

Maybe darken the corner on the rendered one?
