When I learned about this tool in the importing data from csv course, at graphacademy; this tool caught my attention and I think it would be good to continue working on it in more detail so that we never have to use cypher to import data from a csv file.
And get to the point in a future of being able to connect Neo4j Data Importer to your relational database directly extract all the data from the tables and so on, and manage everything then do the import in such a way that the data importer is just an intermediary that allows you to convert from sql to graph, directly connected to both databases, without the need for csv, cypher or other files
