It would be a nice way to show when new data appears or if we had some enhancements to layout parts such that we could expand or close individual sub-summary parts and if those could be annimated that would be cool.
In general being able to also include some CSS animations in places could really add some visual information.
Also in the area of charting for example. What if we went from record to record and the chart coudl animate to show the differences.
There was an article I read recently (I'll have to find it) but it said that people can spot changes in say a chart with movement.
