Adding a back button to the import records pages would be very helpful. There are many times I have gone through and linked all the necessary fields and gone to the confirmation page and realized I needed to change something, only to have to exit and start all over again.
Agree with these. The thought that I can import a bunch of records and if I made a mistake I can't easily undo it is a bit scary.
It is easy to make a mistake when importing records. An undo button would also be nice, (if its at all possible).
