Some of my folders and projects have many tasks. When I scroll down to see the lower ones, the toolbar at the top scrolls offscreen with the highest tasks.
It would be great to have this area pinned so that wherever you are looking in the list of tasks you have the ready ability to change the filters applied or to quick add a task to that folder.
It would be a great feature to this feature to have this as a selectable option. I sometimes work on a tablet with a smaller screen and being able to choose how that real estate is allocated has a lot of merit.
