I had 33 logons to Yahoo, all were legitimate, but, obviously, I didn't need all of them. But, there was no way to do all at once (except for the current one, of course). So, I had to scroll through each and every one in the list, then click one of them, then click "delete", then click "are you sure" (or whatever). Very tedious. Add a "delete all but current" functionality, or a checkbox next to each with an "all or none" option, after which the user can decide which to select/omit. Thank you.
