With more quests requiring us to fly to specific areas, it would be nice if the marker and player created waymarks/flags could change based on your current altitude so you can see if the spot is above or below you. Many games with mini-maps use this feature and makes it easier to find where I need to go, so I hope this game could incorporate it in the future.
I'mma have to mention "that" game, but WoW does this fairly easily with a simple ^ or v arrow next to the marker when you hover over it, if it's higher than you, it has a ^, if it's lower it shows a v. it's fairly light graphically, and makes things much, much easier to navigate to when you need to find something. subsequently, if something is underground in a cave, the marker will dim, as well, but that's just a little icing on the cake, really.
as I read back, I realized I didn't directly say what I was meaning to; I would like this sort of thing in this game as well, as it's really a nice QoL change
I see no reason we can't have a simple icon indicating whether an objective is above or below you. I know sometimes even in non-flying areas in the past, I've had trouble finding objectives because they were in areas with multiple elevations due to terrain/buildings/caves.....
