Is there somewhere on the editor, when doing replacement text as an example, that shows how many listings I am trying to edit and how many of those were affected by that change?
On most of the editors there is an information display box in the upper tight hand corner. This should give the number of changes that will be uploaded and then the number that actually were changed. If a changes is NOT successful then that should also be displayed in the information box.
I've been working on a common display and mechanism. If I've missed one let me know!
