The node based calculation editor is neat, and offers a visual way of building quite complex TS transformations and calculations. But, the “visual complexity” grows quite fast, and I am missing a basic feature common in such node editors where the user can add colored boxes with a title behind some of the nodes. In this way we get some structure and documentation into the calculation, and it becomes easier for the user (and other people as well) to quickly understand what exactly is being done.
Here is an example from Blender, which uses a node editor to build complex ray tracing models:
