@benlau, thank you for the update.
A method of adding Notebooks to Shortcuts might be very useful? For pinning a current project, Inbox, etc.
@bepolymathe, this is a way to add searches to Shortcuts, using the Embed Search plugin
Create notes for the searches you want using the Embed Plugin, and then just drag the notes to Shortcuts.
Here are a couple of examples, with the Note Title, followed by note contents, the contents being the search instruction. This will show the search results in the rendered view of the note. Hope it helps.
