I was teaching my 75 year old father how to use the Cowtool this weekend and he loves it! Thanks, Cow!
I want to pass on his suggestion: can the pre-filled text in the Origin, Destination, Stopover, etc boxes be in a different font/color/size? Currently, it's easy to confuse the pre-filled text with the manually entered text. Perhaps the pre-filled text can be moved into the parenthesis like it is for Dates
