[RainbowCord] [Feature request] Toggle mentions + only RGB

[zerox003]

Being able to toggle mentions on/off (as shown below) would b nice to have :D

Also, removing the white from the color cycle would be great as well!

While you're at it, it would be a great addition if you could add in general rainbowy stuff to the highlighted stuff (e.g. mentions of channels or maybe even links) :>
