Hello there
I have made an OmniFocus action that takes one or more selected projects and creates project folders in DEVONThink (To Go if you are on an iPad as I am)
Link to the folder is placed in the projects notes to honour contextual computing (thank you for that term @MacSparky)
Customisation:
You need to replace the variable dtFolderId with the ID of the folder/database where the project folders is to be created under. That’s all
I hope this is useful: Create-folder-in-devonthink-for-seected-project.omnifocusjs - Google Drive
