If you use long cable numbers you can sometimes see a problem with arrow-style circuits where the cable number overwrites the socket text. Here’s how to deal with that.
Well that doesn’t look very nice…
Select the arrow circuit and drag it out a bit
You can move the arrow end by dragging the blue handle shown. The number follows to the end of the arrow. Do the same for the reverse arrow too.
The reason cable numbers work this way with arrow circuits is to avoid cable number clashes when you have one output feeding two different inputs i.e. a split. Or where a cable loops in and out of an IO socket e.g ring intercom systems.
