1) Live update plug-in for PS. So i don't have to save out and reopen TG after any change in a PS file being used in TG, especially Image Maps.
2) A Simple Shape Pen Tool. For drawing simple shapes. Much like in Adobe illustrator.
3) A button that finds any mistake I make and warns me before I post for help, and which then makes all my projects awesome with one click. I believe this is called an "easy button"
