I would love to be able to constrain the proportions of images when I type in the size of an image. At the moment, I have to use a calculator when I am typing in exact numbers.
Just say an image is 233 x 468 pixels and I want it to be 200 x ??? pixels... This is when I would like to just have an option to constraint the proportions of the image and have the other number worked out automatically.
The reduce/enlarge by percent comes in handy though.
