That sounds like a good idea.
The workflow works great so far! I wonder if you would consider adding an option (if this is possible) to work with multiple .taskpaper files? In other words: have the option to set multiple documents with d:setdoc and then add an extra navigation layer where a user first selects the document before drilling down into the projects within that document?
I typically have several docs open for personal and work related tasks and I imagine this could be useful. I realise this is asking a lot though so just an idea, unfortunately I’m not a programmer so it’s difficult for me to contribute to the project myself.
