please can you add this feature to WP Smush PRO?
Smush (or restore from .bak.jpg) just one thumbnails - for example image-125x125.jpg
It will be very usefull because of plugins like Crop-Thumbnails - https://wordpress.org/plugins/crop-thumbnails/ - where you can edit every thumbnail image to better fit its size. But for now when I crop one thumbnail, smush (with backup option activated) and later I want to crop another thumbnail of the same image, I have to restore all thumbnails and I lost that work.
It could be awasome.
