An important change needed to ACR 8.2b output dimensions behaviour

The 8.2 beta of ACR changes the way that resizing from raw works. In older versions, there was a menu of fixed output sizes which I found very convenient. The program remembered the last size chosen for each individual camera or camera type, separately. It was therefore possible to have 16 megapixel files from a very good camera+lens open at 25 megapixel size, but have 16 megapixel files from a consumer camera like the Fuji F700EXR open at 9 megapixels. This has been replaced with the poor method used in Lightroom previously, where a specified output size is entered (for example 3600 x 3600 pixels). This setting is, however, not unique to the camera files it is first entered for. It persists when you open further files, regardless of their raw type. So it's necessary to keep changing this parameter unless you always rely on processing to the native size of the raw file, and to remember if you have used it. Previously, I could use the resize function for one camera and then when opening a different camera's raws they would be at normal size, not resized. The new method is a step backward in this respect and needs to be revised to become specific either to the raw file type, or the camera serial number, in the same way that Camera Raw Defaults can be. In fact, it would useful if this resizing function was recorded in the XML for Camera Raw Defaults and therefore became specific to the camera and the ISO setting, if the user wished. This would allow for example all ISO 25600 images to be automatically recognised and output to a small size such as 2400 x 3600 even if they started as 24 or 36 megapixel sources - many photographers downsize their high ISO and low-light work, and already have special sharpnesss and NR parameters remembered for each ISO in Camera Raw Defaults. Making the output dimensions part of the information remembered by these defaults, instead of being a persistent parameter once entered, would enhance the functionality of ACR greatly (and also Lightroom).
