This functionality would create excellent and slick information widgets, without using to much screen estate. Off course we can use timer utils to accomodate the change of data, but the transitions are not fluent, specifically when we have a dynamic amount of data (2 one time, 6 other time)
Widgets in Android unfortunately cannot do that, even worst, it is not recommended to update them more than once every minute because any update has quite a cost in terms of resources. The only limited animation capabilities of a widget are scrolling and stacking which are not planned in KWGT at the moment because that would require also quite a lot of resources and might also impact too much the editor. This is one of the main reasons why KLWP exists, to give this kind of freedom.
