Yes perfect just what I was looking for. Am realizing I need a "legitimate" IDA Freeware 7.0 way to do this also
. So for that there are no plugins, no IDAPython but the IDC scripting language should be enough to generate GDL files if enumerating all the functions and saving the files separately as can be done by the GUI. Also a method in IDC to save the call graph. The function CFGs and call graph and then GDL can be converted to a more basic format with a simple Python script or any number of graph tools. Otherwise I would need to buy a license. Although after doing that proof of legitimacy my preferred route is still to use the plugin you linked
