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

Tute pohódnoćenje je za předchadnu wersiju přidatka (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?
