We feel the same way. As you have said, we use abstractions to hide complexity in text-based source files, like modules, functions etc. We do the same in the vi

We feel the same way. As you have said, we use abstractions to hide complexity in text-based source files, like modules, functions etc. We do the same in the visual form. Every node in Luna is just a function, so you can "dig inside" it (by double clicking it) and see how it is defined. We hide complexity just by "collapsing" nodes together :)
