I suggest adding the ability to customize any colors and hue in RGB mode to highlight line (string) of text and its background in the "Listbox" depending on the "Inactive/Normal/Hovering/Clicked/Selected" state.
That is, for each state of the line, its own colors (Text+Background) are configured. Can also add a separate color setting for the frame around the line with text. These settings should affect lists in any types of windows.

Such a function feature will be of interest to all those who like to reconfigure mIRC for their own design in their own color scheme.

An example of what it might look like:

Certainly, this will have a positive effect on the appearance of the mIRC and its fashionable attractiveness for regular use.
