quoting @omz, new beta release 330018, restored the ability to open external folders on ios13

Also, I thought I could only create new files in Working Copy, not in Pythonista, because if you add a tab, then select New file..., Working Copy directories are not visible.

But then I noticed that if I first navigate to the right Working Copy directory in the left panel file browser, and then select ’+’ at the bottom, I can add the file in Pythonista.

First, thanks for both responding!
To answer the questions you both bring up:

It does need to be done programmatically, this is for picking a folder from within a running UI.

The Files sheet UI definitely seems to be able to pick a folder...at least, I've seen other apps use it for that purpose. Even pythonista itself can select a folder from the Files sheet for import and other things.

If it's just that pick_document() is restricted to only picking files, and cannot pick folders, that's what I'd want to know.

@TutorialDoctor

I've actually stumbled across a temporary solution using github pages, Editorial, and Working Copy that may end up providing what I need.

Thanks for the reply!

Sorry, was stupid mistake not reading correctly. Is the section to create extensions :( was thinking about file extensions. Opps
