As the current trend for dark Theme has really taken off, except with a lot of YouTubers apparently. I thought a moving background would be an amazing next generation move. There's been not much custom control generated, and like in a browser one can have some pretty cool backgrounds, or with 3-D graphs and such. I, for one, would enjoy a pleasant small ripple/wave effect, if nothing more than to help the aesthetic, I believe it would also be relaxing and somewhat soothing.
