For several years now (since whenever Cloudplay was added), I have been waiting for JRiver to make the Cloudplay view look like every other view in a skin, which is to say: use the graphical skin elements that skin author's have so diligently put in the time/effort to create. I find it visually jarring when I load Cloudplay, as its style is completely disconnected (graphically) from the skin itself. In addition, if you use a dark skin, switching to Cloudplay is blinding due to its current default white background (and far worse when using MC in a dark room).
About six months ago, I mocked up what Cloudplay could look like with my DIB skin, if Cloudplay used DIB's features and colors (comparison pix below). I decided to wait for the next MC update before posting this, in the hopes that maybe this time it would get updated. Since it hasn't, I guess I will make the official request.
Here's hoping that this is the year JRiver makes it happen!
