Have you ever tried to VOID a door? I have by writing Void on top of the schedule...it's ridiculous. I think that VW's version of Excel is an affront to real Excel, it offers nothing in comparison it could be really cool. It also took me awhile to figure out that VW provides boxes around the cells by default-- where Excel doesn't, so for the longest time I was getting really thick dark lines around the boxes. I once tried to automate a door schedule and it freaked out! Schedules are essential and controling their appearance, as VW hinders, is a bit of a problem. If we are designers flexibility is essential, it is afterall information design that allows us to communicate effectively on paper.
