I think it would be great for users to be able to make their own functions.
for example as a text I made a definition that finds the centrepoint of a triangle and fits the largest possible circle inside.
It would be useful to condense this whole definiton into one neat "function box' with input and output stream(s). I know there is an option to 'compress' the definition but still in a larger definition that can easily become quite messy and confusing, I would rather see it similar the VB component, with the option of "opening" the definition and edit it.
I am attaching the definition, maybe there is a much simpler and more elegant way of doing this ...
