I would really really really really love it if there was a way to automatically run "regenerate thumbnails" automatically after an image was edited in the edit media thickbox. This way, when an editor uploads an image and crops it, for example, then he doesn't have to leave the article page and go to the media library in order to regenerate thumbnails for an image he just uploaded.
This is a necessity, because silly WordPress core does not handle custom image sizes when you, for example, crop an image. Although it says "apply all changes to all sizes" - it in fact does not do that for the sizes added via add_image_size().... So the Regenerate Thumbails plugin is really my only hope :/
So can I beg? :)
