Instead of sending the current subtree to another file/heading, I would like to search for subtrees in other files and insert them in place. Is there any tool offering this functionality?
My wish is to have a directory with beamer/reveal presentations written in Org. When I'm writing I new presentation I'd like to reuse slides from other files. I'm aware of #+INCLUDE, but each presentation may have it's own idiosyncrasies so that small slide modifications are always required.
