This is a plugin to export portals to different formats.
At the moment we support export of all portals in the current view, bookmarked portals by folders and portals inside a polygon
As formats we currently got: GPX, CSV and export for Maxfield
(check out http://www.ingress-maxfield.com/ for information about Maxfield)
IITC needs to be installed. See this page for information: http://iitc.jonatkins.com/
Additionally the "Bookmarks for maps and portals" and "Keys" plugin are needed for full functionality but the plugin also runs without them
For installation just click on this link:

Normally Tampermonkey (or the extension you are using for JS) should recognize the format and ask to install the plugin
