Adding a rotate function to the texture menu in brush settings would be great. I always was surprised with how little control you have of the position of the actual texture photo of the brush and was happy to see some slight improvements on the texture controls in cs6. However besides scaling the texture photo, you cant do much to control its placement. I often find myself making temporary brush/tool presets (btw it would be great to be able to replace a current tool preset instead of constantly deleting them/recreating them to have the same name) for certain jobs with different rotations of the texture simply because I get tired of going into brush settings and swamping the texture everytime. The ability to "Edit" the texture would be great as well.
