Thanks for the prompt, will give it a try soon. Your Pythoner Add-On example also nudged me to think about how to manage the Media Bins more broadly as I move towards assimilating larger libraries of - say - Midi files, like these open source examples: free-midi-chords
A programmable option to import and remove path items from the media bins is what I am thinking right now - but early days in creating interactive experiences with such large suites of media options. It may be more about opening and closing Isadora files with segmented regions based on - for example - musical major and minor keys.
Best Wishes,
