Validate staff data screen filter/sort
On the validate staff data screen, it would be nice if it could remember the last filter/sort used. After correcting an error, I validate in order to remove the error fixed. When I went to correct the next error, the filter/sort were gone.
We now have a link on the left of the Validate Staff Data that says "Go to Navigator" it will allow you to page through all the validation issues one at a time using the sort you applied before you entered the button. It's not exactly what you describe, but I think it would solve your problem to use this.
