To cycle or not to cycle?

[LFDM]

Not sure if it's better to cycle when there is no next thing. or just throw the error, but catch with re-entering the submode we just were in.

Currently thinking cycling is better.

Perhaps you can do like wrapscan which cycles but also displays a warning message, so the user is aware.

Also like wrapscan, you could make the behaviour optional, so users can choose if they want cycling or not.
