Change Colour of Text Container on seen Text

[CakeVR]

Describe the solution you'd like When the player reads an already seen text, the text background/container turns to a different colour. This can be toggled in the layout settings.

Additional context Some Visual Novels do this, it helps to confirm whether this text has been read already. Usually the Skip-toggle is unavailable on unseen text, hence this is a bit redundant, but it helped me a lot in the past. It can be disabled by player whenever I encountered it.
