[0] I suppose Rhombi symbolize choice. But where are the branches? What if "Already Done" is true? Or does the else-branch enforce implicit fail-state somehow?
[1] What's the difference between parallelograms and squares?
[2] What's the scope of the "For Each Issue"?
[3] Why is the second output of "Copy Webhook" named ("output1"), but not the others? Are they implicit default output (maybe "output0")?
[4] What happens with longer pipelines? Do you wrap or have a scrollbar?
Furthermore the size of the modules have same size, so one gets into rendering issues (e.g. the names of some nodes don't fit the "boxes"). Sorry, I didn't want to sound harsh, I just think that visual programming is not automatically simpler, just because it doesn't use text (at least directly - one has also to name "modules"). You also don't use the "free-canvas" in its extreme form I described (where you can rearrange everything), as you've e.g. implicit edges between nodes, which is a good idea probably, as users get a feeling about the complexity of pipelines by measuring their length (which would not work if there are different lengths for edges).
