I like what this plugin does for my scenery, but I hope the developer will consider adding the ability to adjust or tweak the included themes beyond just the vignette. There is a Power User setting that allows you to adjust the look, but when you select it, the theme is dumped and you have to start from scratch. I would like to use the theme as a starting point, and have access to the power user settings to adjust it. Then I could save and call up my new custom setting at will. If I could do that, I would give it 5 stars. Overall though, it is a very nice add on that does not appear to affect frame rates at all, but allows you to enhance the look of your scenery.
