Two changes. (1) The >> "propagate all from this port" moves out of the gutter and onto the
input port row, after the column count: [ in-1 6 >> ]. (2) Fold a port
(click its chevron) and its columns hide; every edge that touched them now converges on a single port handle
next to the port row — visible only while collapsed. Try folding in-1 and out-1.
