Would be nice if in general the data import errors were more user friendly. Eg. error as it couldn't find Company type - would be good if it included a link to where these are configured.
A warning would be nice to say that spelling has to be exactly the same or that blank spaces will cause an error.
An explanation that the fields need to be ticked if you want them imported (useful if you download the template but work on it for a while) or maybe have it automatically do this by looking at the fields in the template?
