The new built-in functions are excellent! I think this design is overall much more usable and tidy.
First question: The old functions used to be able to check the Return Value of the last-run function with "Function.ReturnValue". Is this no longer possible with the new built-in functions? It always felt slightly kludgy to me (with the non-specific reference to a function just based off of it being last), but I did end up using it here and there. Is there a suggested method for doing something similar with the new functions?
Second question: I'm finding that not all built-in functions I've created show up in the "Add 'Functions' action" window when I am trying to call them. Is there something that would cause one to not be shown on that list, or is this just a bug?
It just occurred to me that maybe my questions are related: Are functions with return values not able to be called as an action, but can only be used in expressions?
