[Design] Making mine/ not mine visually obvious

[Dan Steinicke]

I was initially confused about mine/ not mine and expect other folks may 
have the same problem.  Currently the little doughnut after the 
collection name gives an indication of mine-ness but it is not 
intuitively obvious what it means. 

A way to make this obvious could be to have the 'my calendar' and 'my 
Items' display as more of a container and other collections could be 
either inside this container or outside of it.  If we did this I would 
think that it would be so obvious what was happening that nothing else 
would need to be done to explain 'mine-ness', people would just 'get it' 
without explaining.

I asked Mimi about this and she explained a bit about spheres as a goal 
for post Chandler 1.0 features, but then asked me to write this email so 
we could perhaps revisit this issue and consider doing something more 
than what is currently done but stop well short of a full spheres 
implementation.
