Quick actions in Obsidian from anywhere using Alfred on macOS

Obsidian 0.8.15 introduced URL scheme (“obsidian://” and “obsidian:///”) and it makes building Alfred workflows so much easier! I’ve created a really simple workflow that uses URL schemes to open vaults, open daily note, and search for notes (all notes, recent notes, or today’s notes). Download it here and check out my Github repo for some instructions on how to set it up on your own computer. Edit: The workflow has been updated to work with Obsidian 0.9.0’s new url scheme.
