Use deltas for multivalue fields for showing the summary

For end users, number counts start at 1, so you would need to do +1 for number display.

Indexes are typically in square brackets such as:
Paragraphs [1] > Text
Math would put the index into lower, such as <sub> tag.
Paragraphs ₁
^ I think this is best. :-)

If not, we could try to remove that bracket noise completely:
Paragraphs > 1 > Text
Paragraphs - 1 > Text
Or even remove the Arrow noise too?
Paragraphs - 1 - Text
Or we could look at some extremely slim unicode arrows, just some quick examples, there are more:
➢ ⤇ ⦊ ⭢ ⮞

OK Cool, committing.

Discussed follow-up: we should remove the index if cardinality 1.
And i still feel like the " - " can be more compact and make things more clearly belong together if we use a UTF-8 arrow and even remove the spaces...
