I would also implement a "catch-up log". It bugs me to no end that I'd be in the middle of a glorious cut-scene and the message "Your have sold XXX item for YYY gil on the market" pops up right in the center of the screen. Same for retainer ventures.

I wish we have a "catch-up log" that pop up once we come out of cut-scenes and list these messages as well as any tells we received, any system-wide messages, etc.
