I would like to recommend an increase in the size of the kins list so that an individual can actually have everyone they know in the list. This would make it much easier for keeping track of your villagers and trading friends. Else it is more of a random guess in trying to get in contact with them. or having who seem to be randoms walking around your village that you cannot know if you still want to know your trader friends and visa versa.
Recommendation: add a scroll bar or something to kins list to increase its holding capacity.
