I just came across https://tokie.is/ (Tokie)
I’m intrigued by the way they use a file in every finder folder to provide Tokie with instructions on how to render a folder view. This enables inline previews of HTML (allowing for widgets), rendered markdown previews, custom metadata and labels etc.
It struck me that DEVONthink would in theory be able to support Tokie’s format (since it’s file-based) and render Tokie inline previews and list views with custom metadata.
Potentially this would allow users to optionally create folder views within DEVONthink that function very similarly to a Notion page or similar.
