0.1.1

On-screen text now scales the way the game's own HUD does: by screen height and the game's GUI scale setting. It used to grow with the screen's width too, so on ultrawide screens it came out far too big, nearly twice the game's HUD at 5120x1440.
Sizes now match Odin's Long Drop: at 5120x1440 the text is about half its old size, and on a 16:9 screen about a third smaller. TextScale 1.4 gives the old 16:9 size.
TextScale (1, 0.5 to 2) sizes Odin's remarks, live.

First release: Odin shuts the doors you opened this session, through the game's own door use, once there's a reason to and CloseDelay (2 s) has passed.
Reasons, each with its own switch: an awake enemy within EnemyRadius (30 m) of the door (CloseNearEnemies, on); night and the last DuskMinutes (2) before it (CloseAtNight, on); a raid whose area covers the door (CloseInRaids, on); the horn from Odin's Dusk Horn, if installed (FollowDuskHorn, on).
WalkAway (off) waits until you're WalkAwayDistance (10 m) from the door. AlwaysClose (off) shuts doors in daylight too.
Never while you, another player or a tamed creature is within DoorwayRadius (2.5 m) of the door; never in dungeons or locations, on doors that need a key or can't be shut, or on doors you didn't open. Exclude names doors to leave alone.
A short remark from Odin when he shuts a door (ShowRemarks, on), at most one every RemarkCooldown (30 s). No keys.
