Vertical text in columntitles
 

Hi. Is there any way to get vertical text in the column-titles? If not, this would be a killer feature to add (for me anyways). I have lots of checkbox-columns and rating-columns (1-10) for a journal of some sort, but it does not work very well as I have noe place to write much in the columns.

Semi-vertical would maybe be even better, but I guess cocoa does not support it.
