In the standard Advanced query filter dialog, when you select a field to filter, standard lookup displays only a field label. Sometimes, it is more convenient to filter by field AOT name(and not by the label).
This tool adds a new column in the standard Field lookup dialog, so you can search the required field by label or by AOT name.
UPDATE - the same field was also added into the "Personalize-Add columns" dialog(thanks @wojzeh for the idea)
