 ### New
 - **Accurate without the DLL.** OctoBus now ships with each route's restart offset (how many seconds into its trip it docks, counted from the last server restart), measured on 12 October. At every login it asks the server how long it has been up and sets every route it has not seen since that restart from the restart time plus the offset. A brand new copy with no DLL and no sightings gets every timer right from the first login, and stays right after later restarts.
 
+- **Settings window**: `/ob options`, or right-click the minimap icon. Background opacity, window opacity, text size, window size, lock, which corner stays put as the list grows or shrinks, auto-show, which routes to show, and bell alerts. Changes apply at once.
+
 ### Changed
 - The "no DLL: estimates only" note is gone from the panel: without the DLL the timers are now accurate. `/ob debug` still shows whether the DLL is loaded.
+- The footer no longer names the route with the oldest data (the restart correction makes it unnecessary). It only appears after a server restart, while a route in the window has not been seen since.

 - **Auto-show**: the window opens by itself at either end of any route (the zones in the table above), and while a tracked transport is in view, such as on a crossing. It hides elsewhere. The icon toggle always works manually. Add more auto-show places with `/ob allow <zone or sub-zone>` (capitals do not matter; `/ob where` shows the names), remove one with `/ob disallow <name>`, or turn the behaviour off with `/ob zone`.
 - **Bells**: click a row to toggle a bell. Belled routes print a chat message `/ob alert` seconds (default 45) before the transport docks at the row's start, e.g. `Orgrimmar -> Undercity: docks at Orgrimmar in 0:45`. Nothing is printed to chat for routes without a bell.
 - **Reverse a row**: right-click it.
+- **Settings window**: `/ob options`, or right-click the minimap icon. Background opacity, window opacity, text size, window size, lock, and which corner stays put as the list grows or shrinks, plus auto-show, which routes to show, and bell alerts. Changes apply at once.
 - **Move and size the window**: drag it to move it; drag the dots in the bottom-right corner (or use `/ob scale`) to resize it. `/ob lock` locks position and size; `/ob resetpos` puts the window and icon back at their default place and size.
