Nice.  I got a chance to play with it and I like it.  A couple of 
comments:

1) The use of s_tile_get_objectlists nicely simplified the search.
2) It might be nice to put an indicator in the status bar when it is on/off
3) The circle indicator suffers from the inverse problem as the grip boxes
   (circle drawn constant size, so they looks tiny compared to pins
   when zoomed in close).  Maybe this is okay/better than the grip
   behavior (which is really large boxes when zoomed in close).
4) I like the circles as the indicators though. :)
5) I like the behavior but I don't know how it will be received by the users
   at first.  What are your thoughts on if it should be on by default?
6) Also, I haven't made up my mind which parameters we need to expose in
   the rc file.  Maybe just the enable at first and see what kind of 
   feedback people have.

Feel free to merge it to main git repo (I've looked at your code changes
and they look just dandy) so that it gets some more exposure.
