Hi Joe, thanks for the kind words!
I don’t use SO myself so I have to judge from skimming its docs. I think Shimmering Obsidian gets you up and running in a very short amount of time since it basically brings a lot of new Alfred workflows to the table. Actions for Obsidian gives you a number of building blocks to create your own Shortcuts workflows to make Obsidian work with other Shortcuts-enabled apps on macOS & iOS. I believe you could recreate most of SO’s features using AfO’s Shortcuts actions, though.
