I'm happy to make any tweaks to the layout, colors, sizes of the dots,
spacing, etc. If design can provide a mockup, that would be great!
But if not, I'm happy to take suggestions and try to improve it.

I wanted to stop drawing something big every frame while the activity
is trying to start; that's the supposed performance improvement.
Blinking would be fine, or a brief fade in at the beginning.

No - the clock just displays one new dot per second. So an activity
which launches in 3 seconds shows 3 dots.
I could implement some estimation capacity, but that would mean the
dots appear faster or slower. I prefer to let the user see there is a
different amount of work involved in starting each activity, instead
of implying that the same amount of work is being done at a different

The way it's implemented now, the kid has to remember how many dots an
activity takes to start up. But I think that could aid children who
are learning to count :) (WARNING: Heresay!!)

I did some work towards this, with a patch ready for 0.88, in
http://wiki.sugarlabs.org/go/Features/Problem_Reports. I will
definitely make it automatically save the activity log to the Journal,

Blinking would definitely be ok.
