[Feature Request] alternating backgrounds for chat

[Beariddle]

It may not be a high priority feature request, however, having used this feature on multiple apps throughout the years, I do find it useful for reading within chat applications.

Currently, the background of the chat is just one colour and fast moving. For some, this Quality-of-life feature helps with reading chat a bit more clearly by adding alternating the backgrounds of each message. One is let's say black (in the black theme) then the next gets a transparent gray, and the one after back to black and so on.
