After a couple of hours working with these patches, my feedback is very positive. Besides some visual glitches when creating a new heading with org-expiry-insinuate activated (which automatically adds :CREATED: properties), I could not detect any side-effect so far (will keep testing). The visual glitch looks like that: :PROPERTIES:X:CREATED: [2020-05-04 Mon 18>54] X ... with "X" being my character that symbolizes collapsed content. The way it looked without the patch was a simple collapsed property drawer. To me, this is acceptable considering the huge performance gain I got. THANK YOU VERY MUCH! I can't remember where I had this way of working within my large Org files[3] since ages. >> Anyway, the real fix should come from Emacs itself. There are ways to >> make overlays faster.
