Different save points for different locations. For illustration purposes, the video shows the enabling/disabling animations.A save point may be disabled during a boss fight, for example.  Most checkpoints will, however, be permanently enabled (no switches and such) and simply passing near the orbuculum will autosave the game. The user will be able to create a named save by pressing a key, but this is not yet implemented.

(I am still busy with other work but took the time to implement this while not much was happening.)
