Is it possible to include the "Size" column or other columns when exporting to "just index"?

This review is for a previous version of the add-on (14.0.1).

Thanks for the review!
Currently the fields exported are fixed. I think I know what you are asking for, however, some clarification is needed for this.
Can you post an issue in the repository where we can discuss?
