Within the Kanban view, you can drag and drop the branches to place them into the Low or High priority columns. As this information is now visualised, it can help you with where to focus on the higher priority tasks within your project.
Alternatively, you can change the Kanban view to show the levels of completion.
Click on the Kanban Completion button 
The view will change to now show columns labelled Not Started, In Progress and Completed. Again, you can drag and drop the branches to different columns. This can help with showing you where you have yet to start work.
