I'm not sure if this has been discussed here yet, excuse me if it has.
Anyway, I've noticed that you've gotten "hover-colors" for the W7 taskbar, and this is great, but most of the time it's showing the wrong color.
I think the problem might that the applications simply aren't assigned any color yet, and due to that given the default gray color. Some applications this affects is; Steam, Resource Monitor and Remote Desktop (3 things I normally got running one way or another...).
It's not a big thing, but just thought I'd mention it
edit: Also, one other thing. The taskbar's hover-color on updated windows seems to have some sort of malfunction. The color overlays the "announcement"-color. I don't know if this is a bug?
Thank you for the feedback. I've adjusted the hover colour to look better for the next release. Also, I've stopped showing the hover colour when a taskbar button is flashing. Thanks for your good eye.
