Heya!

I really like those two ideas, as they would solve problems of annoyingness with some players. I can see them live together as alternatives.

1. Purchase something with the Retainer's money. If its inventory is full then it will show that it's not possible.

2. Select the Retainer in the list of the Item Search and port (INTERACTIVE CHOICE!) Into its Ward ・Before its feet

I like this very much, and I can see this ideas seeing the light of the day!

See ya!
