It would be really helpful to be able to create new layers, set blend mode, etc via script as well as assign script to a hot-key. I've created a complete workflow environment in Photoshop with a custom palette, scripts, and actions which greatly minimizes all the pointing, clicking, pull-down menus, etc. and allows me to spend more time 'painting'. Not sure if you view this as a goal for ArtRage.
Thanks for considering this.
