Exporting on as .png file is limiting in the sense that you actually have to crop the exported figure to have it fit nicely in a word document. Scaling of the figure also leads to a loss of quality. The grid in the background should also be removed on request.
As Microsoft word is largely used to create documents for students, the possibility to export as metafile would be useful to teachers.
p.s. Word does not fully support svg files but "export as .svg" would still be a nice option.
