I would like to have 4 new kinds of window bricks that are arches. I want up and down arch windows that have edges like the normal window. And I also want up and down arch windows that have edges like the normal window except that the flat part doesn't, so that you can connect them with other arch windows facing the other way. Also I want for each of my types of windows to have multiple sizes, all the sizes that the normal arch bricks have.
