[Suggestion] Color picker wallpaper tool

Have a color picker style tool within the settings page that lets you create a solid background with the option to add a gradient.

To keep this polished and consistent, it’s acceptable to have only a few colors to choose from that are on theme, with the permanent addition of black. Gradient can be added with a click, in a fixed position. Gradient might also evolve with each release. Maybe a watermark overlay as another selection.
