Ctownwoody I think that's a good idea, it's annoying scrolling down past all the desynths. There is a huge space to the left that is free, perhaps putting a seperate column for desynths there? Just a thought.
Chaupire at the Woodworking Guild sells Lumber for at least 72 gil. It will go up the less he has in stock. The guild in Al Zahbi also sells in a similar way.
