Hmmm, just noticed you answered one of my questions, that I again stupidly asked (and have since crossed out) but could the character icon for a mounted character be on the line between were the front of their mount and the rear of their mount to make it easier to tell if they mounted or not, and exactly what spaces the mount is on at a glance (I would advocate the possibility of making some kind of bookends for the horses but this is needless work, lining them up over and over again I would think)
Also, how is a horse handled at a diagonal? would it take the 10" by 10" normally taken by a large creature or would it allow other creatures to get along its sides? and it it if the latter: can two Diagonal horses make a square by being 'beside' each other?
