The incorporation of an overlaid "banner" on the cover art can significantly enhance its utility. This addition could be particularly beneficial for distinguishing multiple discs in a set, such as CDs labeled "Disc 1," "Disc 2," and so forth. A banner displaying the disc number superimposed over the cover art, which could be toggled on or off, would facilitate the quick identification of the disc number currently in use.
This concept can be similarly applied to DVDs, Blu-Ray, and 4k UHD discs. These could feature a banner over the cover art denoting the specific disc format type. This enhancement should be implementable as a straightforward checkbox in the cover art editing interface. Standard banners could be provided for common uses, along with a few basic options for customization such as positioning (top or bottom) and transparency levels (semi-transparent or opaque). This would offer a balance between standardization and personalization for the users.
