It's a great icon theme, but there are a few things that could be tweaked. For example certain system icons don't show up because they are too light. For example the close and open with buttons on notifications inside of the system tray. In dolphin the go back and go forward buttons do not change to an active white color when those commands become available. Instead they remain in the inactive color state. Lastly Some icons in the toolbar of dolphin and other qt applications are not visible at all. I can send screenshots if need be. Personally I am using the kvantum theme engine ,so that may be part of the problem. Anyways like I said before this is a really great theme ,and I hope to see it continue to get better. I'll be donating a dollar anyways. Thanks.
