Improved productivity with "Next actions" Folder

There is a way of working with Nozbe that is not fully supported, but that i find very useful in terms of productivity:

Once a task was marked as done in the “Next” folder, the next task in line from the same project will be automatically loaded. This way, during work time you always have the next thing in line from every project in front of you.

This is now possible only if you star all tasks, and check the box to display only one task from each project. I think there should be an option to make this default. For me it works wonderfully.
