quick one: Please, who knows an idiomatic way to select a previous or next element in a collection in Kotlin?

```
val list = listOf(...)
val current = ...
val next = list[list.indexOf(current) + 1]
val previous = list[list.indexOf(current) - 1]
```

I don't think you can do a lot better than that.

sounds like you want a doubly linked list

Look at methods that `ListIterator` has
<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-list/list-iterator.html>

But this would help only if iterate to your `current` element through this iterator, and not just getting `current` element from outside.
