It would be useful for collaborators to easily filter or sort Notes so they don't have to wade through information that is not relevant.
Its currently possible to move and sort Notes through a parent/child hierarchy. One workaround would be to use a naming convention for notes so that they are easily sorted and viewed in a way which makes it easy to navigate.
At this time, because of the available workarounds and current priorities, we are unlikely to make changes in this area. We hope you can understand.
