Even images support in Emacs (which is admittedly young and unevolved) already supports advanced features like :pointer and :map (see the node "Image Descriptors"). And I wasn't talking about simple text properties that just change faces or the size of the characters, of course. What about properties that need to evaluate Lisp forms or depend on Lisp-level variables? > I guess it does not directly has something that reminds of "special > properties", but would that be hard to add?

The difficulties is not with searching, the difficulties are with maintaining many overlays.
