In Filemaker, the access to the data, I think, is very GUI-based.  
Otherwise, why do we need to create web-specific layouts? I'm betting  
it does make a difference. I doubt a few text objects would make much  
difference ( I will sometimes leave headers in my web-based list  
layouts), but what about a biggish form layout with a graphic or two?  
This really does need tried and tested. (points finger at rest of  
list  ;-)
