It seems that there are times where the import doesn't fail or generate an error, but the import may not work the way the user expects. It would be helpful to have a checkbox when doing the import that would generate a detailed log file when checked, whether or not there are any identified errors.

As examples, which I will create a separate issue for, I am trying to import a csv file and one of the fields is not being imported. There are no errors. In one case, I was informed that there was no new information. In another case it says that all users were imported but the field is still empty. There is no log to examine to see what happened.
