There is an idea to make the text underline colored. It would be great, for example, to underline words containing spelling mistakes in red, or just highlight what is worth paying attention to, but not color those words.

As with the color code, a color number is added to the key combination: "CTRL + K + 04"

In the same way, you can add the ability to add a color shade number out of 99 possible after the key combination: "CTRL + U + 04" so that get the colored underline of the text.

An example of how it might look:

Is there a way and the ability to officially implement this in the mIRC client?
