Feature request: Support for Curves in ACR

When shooting film it's commong to scan the negatives and obtain a DNG file from the scanner that stores the negative image. What I generally do it to them load the file in Adobe Camera Raw and invert it using a Curves adjustment. This change is dutifully displayed by Bridge both for the thumbnail and the viewing of the image. It would be great if FRV would support this feature. It is really the only thing that would allow me to finally stop using Bridge.
Thanks!
