Spawn points were added to maps a while back, which made going to specific places ingame that much easier. But, something that hasn't been done are user-made or "custom" spawn points. Where someone can go to a point in the map and save that position, so that it can be spawned to on a later level load. I know its small, and probably unimportant in the grand scheme in this game, but it would be a neat (if not convenient) addition.
possibly within some sort of external editor, or even with the map editor that could have an option if you play around with it i dont know. There are custome spawn point for bigger maps already, and maybe there should be a template one like how they have for maps... so people can go into the files and maybe type in coordinates lol idk
