It would be great to choose whether or not the Crop Tool (R) recalls the previous aspect ratio. This way, users can set whether or not the previously used aspect ratio is automatically called up after activating the crop tool (pressing R) or if the crop tool defaults to the original, or any other, aspect ratio.
I realize a Crop Ratio is available in the Quick Develop panel, but that's a bit cumbersome as the general crops need to be made before working through each photo. Some users like to crop as a last step after the bulk of other adjustments have been made.
The option of utilizing the following workflow would be great:
Make various exposure adjustments
Press R
Mouse over to Crop dialogue
Select 8x10 ratio (for instance)
Adjust new 8x10 framing
Press R
Move to next photo
Make various exposure adjustments
Press R
8x10 ratio is already activated (because that was the previously used aspect ratio)
Adjust new 8x10 framing
Press R
Move to next photo..
