There is a lot of casual content in the game that doesn't require the usual trappings of a DOW/DOM/DOL/DOH. For example: Gold Saucer, Housing, Island Sanctuary, Idling in main cities to name a few.
Having a UI hotbar, party frames and duty lists often get in the way and ruin the ambient experience for these activities. Having to write macros to remove all of this stuff is quite cumbersome and it feels like we should be able to swap to an "everyday citizen" via one click.
I'd like to propose that we have system we can macro to a button or select from a menu that creates a simplified UI specifically for this casual content, removing all the clutter and leaving a clean interface for chatting, exploring, house designing and saucer shenanigans.
