Similar in function of being able to specify different units on the fly directly in input fields ( px, in, cm, etc), please go one step further and also implement the ability to type in a math operator ( % + - * /) just like Illustrator and InDesign and then the calculations are performed automatically.
For instance, if I have a 2 in x 3 in shape layer, please allow user to input "+ 3 cm" after the "2 in" and Pshop would then automatically perform the calculation (just like Illustrator/InDesign).
Thank you.
