@vanvugt;  the idea behind the having a slower animation to start with
and then increasing in speed during usage is to solve the tradeoff
between "slow clear animation allows the user to see exactly what is
happening, but makes the computer feel slow and is annoying with
repeated usage" and "fast snappy animation makes the interface feel
quick and gets out of the way of the user, but is not so descriptive".

Once a user has learnt that minimised windows live in the Launcher, the
best animation is something super snappy, exactly like we have at the
moment.  We don't want this to change.  However to solve the 'new user
using Ubuntu for the first time ever' use case, an initial slower
animation that gets slightly quicker everytime a window is minimised
should do the trick.  Yes this approach has the animation speed change
over time without explaining this to the user, but at most the perceived
effect will be the computer getting quicker, and in most cases won't be
noticed because minimise animations are the type of thing that are not
consciously watched after seeing them happen for the first few times.
This way we are teaching the user about how Unity behaves, and then
getting out of their way with the minimum of fuss.

This will also need to be tested, so it would be much appreciated if you
could expose 'starting speed', 'speed decline duration in number of
minimises' and 'ending speed' variables (as well as a 'reset' option for
testing purposes), and then we can experiment with tuning these
variables.

Thanks,
John   

** Description changed:

  In user testing we found that when participants minimise their documents
  they don't know where they have gone.
  
  -------------------------------------
  Desired solution:
  
  - When a new user starts using ubuntu, the window animation should be
  slowed down.  However to prevent the slow animation making Ubuntu feel
  slow or frustrating over long term usage, the speed of the animation
  should increase the more it is used, until the speed reaches it's
  current value.
  
  - The speed should increase over the first 100 window minimizations e.g.
  the very first time a user minimizes a window, the animation is very
  obvious and slow, and the 100th and subsequent times the user minimises
  a window the animation has the current fast speed.
+ 
+ - This will also need to be tested and the values refined, so the
+ 'starting speed', 'speed decline duration in number of minimises' and
+ 'ending speed' variables (as well as a 'reset' option for testing
+ purposes) will need to be exposed in CCSM

** Summary changed:

- Window animations are too fast for some people to see.
+ Window management - window animations are too fast for some people to see.
