Not a big suggestion, but one that can prove a bit useful. When in a map that has spawn points, have a new menu item above/below the level button that will teleport you to whichever spawn point you choose. That way, you don't have to reload the map if you change spawns.
You mean changing spawns as in changing by teleporting with F7? If so then just click on "Home" in the radial menu to teleport back to the default spawnpoint you spawned at when you loaded the map at the start.
