True - but i have four columns, with the number of rows being determined by how much is scraped off a website (this is a bugzilla tk front end I'm playing with if that explains it any better). The number of rows could be 3,or it could be 100's, and I didn't relish the idea of a button for each item in each row...bah :) 'Sides, HList has a potential use for a feature I'm thinking of to see multiple bugzilla servers/accounts at once (being able to break it out into, well, Horizontal Lists/trees).

Update: ...which I guess means I just invalidated part of my original post :/ (though the problem with passing data, now understood, was legit)
