Hi, I've been trying to get additional tags from itunes m4a files. for example album artist which should be aART based on https://help.mp3tag.de/main_tags.html

I added this to config.xml

<library-options>
      <id3>
        <auxdata>
          <add-data tag="aART"/>
        </auxdata>
      </id3>
</library-options>

and import.js

var aartist = obj.aux['aART'];

Port Map 2.0.1 (85)
OS X 10.11.6 (El Capitan)

To attempt to reproduce this bug: Click on the "All UPnP Mappings" button, then click on the "Close" button. In my case the close button has no effect and I have to forcefully close the app.

For ESP32 can use the second core as the webserver and prevent delays in response.

Might add a different example for ESP32 or add this as macros to the current example.

It would be good to set it by hash(machine-id, ip, port) or something similar
