I mean to say the numbering system 1, 4, 7-12 to indicate slices of data, not the UI 🤣
other possibilities: 1, 4, 7-rest (“7 through the rest of the slices”) or 1, 4, 7… (“7 through the rest of the slices”)
and provide it as sample input to the user when they first try to print something, that should give them an idea of how to use your numbering system
“Expand on” meaning add new information lol
