I use Irfanview a lot to scan thru folders of images, thinning and sorting dozens or even hundreds of images in a session. I sometimes have a heavy finger on the delete button, and on occasion I hit it once too many times. I used to be able to immediately go to "edit -> undo" and the most recently deleted file would be undeleted. Irfanview no longer does this. I would like to see it (if possible) re-integrated, or perhaps an additional menu selection to "Undlelete last file deleted" under edit.
