I am finding that it would be very useful to get all the information in the list/speadsheet view of the font out into a CSV file that I could manipulate in Excel. If I select rows or columns in that view and copy, all I get are the glyph names. Could you make it possible to either copy this view, or perhaps export it to CSV?
There is a script for exporting the metrics. You’ll find it in my script repository on github.
