The html code "<br>" works really good on translation tooltips.
Adding colors codes can be a really good thing for modding, adding directly on translate txt.
Like this example:
Tooltip_EN = {
Tooltip_Pliers = "<RGB:1,0,1> Can be used to trap a rat.",
}
Or maybe adding directly to scripts.txt
Like this example:
Tooltip = <RGB:1,0,1>Tooltip_Pliers,
