Maybe I'm misunderstanding this tool, but I'm looking for a ui for (technical put non programmer) end users that offers a lot of flexibility. I (the programmer) would create a bunch of partial calculations (the nodes) that the end user then could strong together in advanced and creative ways. The competitive product for the end user is not programming, but Excel.
