What can I do to create the experience of having a folder, I guess deliberately not a part

Thanks for that. I’ve been using Drafts for years and organize with tags rather than Workspaces and often struggle finding my drafts. I set up Workspaces and it’s close enough to folders.

Jut one note: folders can be just conceptual as well as part of a file system. Ulysses uses a database and organizes in folders.
