[0] Kind of. It's a filter, so "false" means "do not advance". We have different Snaps for If-Else (the Snap would have 2+ outputs and you would route to a respective "branch" of the pipeline)

[1] They denote different categories - parallelogram = READ (i.e fetch data from somewhere), square = Transform (modify existing data)

[2] For Each Issue - for each object in the specific, targeted array of incoming JSON object... (basically split the array chosen)

[3] Correct

[4] You can adjust the rotation of each output, so it could snake around. You also can drag the output of one to the input of another that are not side-by-side and it will mark them as connected, so you have layout in any way. Finally, you could split up into separate pipelines and use another Snap to tie them together.

I don't think you are being harsh - I'm not sure there is any way for a visual programming language to be both powerful enough to permit massive customizations and concise enough to be immediately readable. Some level of interpretation has to be done.
