I would like to see a feature, that lets the importer preview the import, before actually processing it with an error at the end, which results in redoing all work from start again.
This would help to save lots of time, especially for starters.
It's very frustrating when finally hitting the import button and it fails all the time.
In addition, a feature to automap would be great to have a quick start.
Also, In addition, a feature that explains where the column data is going to be imported to within WordPress would be great.
My error log tells me now where the issue happened, but not why.
Now I need to guess and test.
