flow New input, output

[sychris]

flow New input does not eject a value box meaning you cant pull a connection off of them. and must use the input or output of another node. this also has a side effect of not being able to make a "passthrough" flow there implementation details get filled out later.

What you refer to as the "value box" is what I call a "pin" (or inport/outport in FBP lingo
Main inputs/outputs can be thought of floating inport/outports.

I'll start with the second issue - a valid (and relatively easy) bug. Creating passthrough nodes is a very interesting motivator for fixing that.

The first issue is more thought-provoking as it raises questions regarding the whole implementation of main inport/outports, which TBH I am not 100% happy with:

1. it's hard to understand
2. it creates issues like a conflict between the drag behavior and drag-to-connect behavior

The only alternative I can think of is a built-in node that exposes main inputs or main outputs, which I am not happy with either
