@@ -35,28 +35,17 @@ New features:
   - see the current direction of the panorama on the map
   - click on a point on the map to see this point in the panorama
 
-- Provide permalink with a given position in an image (to be able to share
-  links like "What do you think <this building> is?")
-  → already done in the PHP/JS version, actually (to_cap, to_ele)
-
 - Create new reference points directly in the panorama view (right click /
   new ref point / ask coordinates, name, etc).  Even better: open a pop-up
   or a new page with a map, so that the reference point can be placed on it.
   We could even fetch the ground altitude automatically, and only ask the
   altitude above ground.
 
-- Allow to define a "default" orientation/elevation/zoom when visualising a
-  panorama, so that it's not pointing at the sky or a tree by default...
-  → it is already better: we point at the middle of the image by default
-
 - Allow to zoom more on tiles, even if this means having a very low quality
 
 - Given a new point (for instance, a new person that wants to be connected),
   list all nearby panoramas that point in this direction, with links that
   orient the view automatically towards the target point
 
-- display the current position in the URL, in real-time, exactly like
-  openstreetmap (so that any link is a permalink)
-
 - ability to click and drag a reference point in the UI when it is not
   at the right place
