This is the functionality that has replaced the My Work section. I've tried this out and don't find this helpful at all.
I like to sort my to-do list by status because we have custom workflows in place. By default, the My to-do section will list tasks from the default workflow first and the ones I want are right at the bottom. I need to manually collapse all of the statuses until I can see the ones that are most important for me.
It would be good if there is an option to save my own custom configurations or at least drag and drop to change the order of the list. Otherwise I might as well stick to a custom Dashboard which makes this section redundant.
