Thank you for the reply! I had forgotten about the Spotlight index setting. Turned it on for the Inbox, and was able to find the test notes I had created that way,
But even better – in messing around in the Inbox, I saw the Move To command, which allowed me to move the note from within DT’s structured file tree and into one of my indexed folders. THAT makes a huge difference.
My use case is to keep the DT tab (lower right) open at all times as a catch-all tool. Then, I can go through the Inbox and move items I create to various places in my indexed folders. Thus, DT takes the place of a number of other input tools I was/am using. AND, I get all the other advantages of using DT.
I realize that for anyone experienced with DT, this seems all too elementary and obvious. But for me, as I was wondering if I had to go back to some of my previous tools, this was a significant find.
Thanks to all for your help!
