TL;DR
Visually distinguish wildcards, when they are acting as literal icons instead of un-filled wildcards.What?
Add a different border color, that lets me see when I've put a wildcard somewhere where it will not ever be filled in, and will always act as a literal icon.Why?
I need to debug my incorrect wildcard usage, but I can't see when the icon is literal instead of acting like a wildcard.I'm desperately trying to figure out where item and signal wildcards can actually be used properly, but don't have good feedback. The description of the item-wildcard says it only checks cargo(1) so I can sort-of figure out when I make a mistake.(2) However, the signal wildcard is completely baffling to me. I've got a combinator at the test-station, that will output the big-demolisher icon when I put an item into the nearby chest. That combinator is wired to the station, and the station has the checkmark to share it with the train. However, the train never leaves its station when a signal is set that satisfies it's condition. See the attached screenshots of my test-loop with the one station with a circuit and one destination station.
(1) There's other threads that advocate for this checking station names, for dynamic dispatch of trains.
(2) This is more obvious, because the interrupt adds a station to the schedule with the wildcard icon unfilled, and when you hover the mouse it says there's no such station.
