Forums Scripts & Popups separate highlights into another window?

does anyone know of a script that would take all your set highlights from the mirc section like $nick etc and put who messaged you or what was said and where (ie channel wise) into a separate dialog window?

or how hard would this be to create ? I know some scripting but not enough to do this I don't think.I leave my irc connected a lot and I miss highlights fairly often because by the time I get back to it the chat has progressed way past the point of highlight.

thanks for any help
