Thanks, Paul. Graphics very helpful and clear.
Your news is encouraging! I am a heavy user of DevonThink (DT), and will give auto-fetch a try.
From a quick-read on another thread in this forum, it seems auto-fetch will work with any URL, including links to web pages (http://) and links to files on the local computer (file://). This means I could auto-fetch files that are in a local folder that syncs with Dropbox. Furthermore, since Tinderbox regularly refreshes the content of auto-fetched notes, the notes in Tinderbox will be kept up-to-date as other apps alter the corresponding files (probably can’t rename the file though... I assume file:// depends on keeping the path and name).
A key missing part is the ability to edit the note in Tinderbox, and have the changes “reflect” back to the file on the local computer. If this can be accomplished, that would tightly integrate Tinderbox notes with files that are edited by virtually any other app on any platform. This would be very powerful.
