listbox help wave

I'd like to be able to specify a text 'help' wave for a listbox, with the same dimensions as the listwave. When the user hovers over a cell with a corresponding entry in the help wave, the contents would be displayed in the same way as the help string for other controls.
My immediate application for this is generate the listwave from a wavelist and the 'help' wave from corresponding wave notes. Mousing over the wave names will then provide the user with some pertinent information to guide their selection of waves.

Wonderful. I look forward to it.
How about my request in this forum for more /NWOK flags, or is that too much to wish for?
