Import pro documentation - please update!

I am active user of import pro. I have latest verison. But when I use download smaple file in the eshhop import proo backend page I see a lot of fields that are not in documentation. For example i have custom_fields column in the sample excel, but the explanation for this column is not in the documentation. The same goes for field tag_name. I was told that you can't import tags or custom fields with import pro? Is there updated documentation for this?
