I think alot of what you're asking for are adjustments to increase the amount of MGP you get. I personally just want more fun games and attractions.

As far as the gate monitors to let you know when a gate is going, I don't see any reason to remove them. I actually look for them to see if a gate is still ongoing sometimes much like looking around for a clock to see what time it is. My in game clock is usually set to Eorzea time (for fishing nodes) and I'm on a controller so I leave it that way. If a gate isn't in progress I just relax until one starts.

Seating around the Aetheryte would be a nice thing to see. Enough people gather in that room but I'd like it to be more functional and pleasing to the eye than it is now.

I'd also want more music to be available throughout the saucer...I can only handle so much of that song before I have to turn my music off.
