Emotes, poses, and the simple act of sitting or leaning on furniture or the environment would be very much appreciated.
While not important, it's nice not feeling like some drone, I sit around all the time in Star Citizen, DayZ, (and others alike) just to take in the environment for my own personal enjoyment, I'd do the same with Elite.
Immersing myself and going out on a 5k+ly excursion, and stopping on a moon during a sunset to sit on a rock or my SRV and eat my lunch or dinner while I listen to calming music. - A warm coffee, a ham and cheese sandwich in the late afternoon with some nice 80's hits playing in the background while writing in my logbook, I'd like that.
