we probably want added text to the end of each journey that can be shown here
Special entry in the fellowship feed, too?
"do you want to continue / start another journey?"
can use "start is same as current end" && "same book" to find continuities
if there are none: offer first unused leg of current book ("aragorn journey finished, continue with frodo?"), then offer first leg of other book, finally list all including already completed
open question: is it terrible that leftover miles are discarded? (imo: probably not, people can always still edit their entries / just add a new one)
do we mark journeys as completed? otherwise, can you un- and re-complete your journey repeatedly by editing your last entry? :grimacing:
What happens when a journey actually finishes?
