Also no support, although I had to think about it for quite a while before coming to a decision. Taller signatures will just make threads longer than necessary, and wider will mess up the formatting of threads for people with different size screens, mobiles etc. I've found browsing sythe on my phone has caused some very odd format issues with signatures being centered and text all the way to one side. There's no need to add to it any further, and we are basically at our limits for now.
