What I think would be very useful is the addition of your retainers inventory items/bazaar/money/etc. to the Retainer List in the Main Menu. It would be nice to be able to see what I already have on my retainer so I know whether or not I want to keep certain items in the field, and also to know how much money/bazaar items my retainer has made/sold so I know if I should go update bazaar list.
I don't expect to be able to actually retrieve items or add to bazaar, as that would basically make having a retainer completely useless, but it would be nice to be able to see what I have from anywhere. Thoughts? Suggestions?
