You may notice that not all of your drawing/analysis tools are visible in the quick access menu.
You can access all drawing tools from the tools flyout menu by tapping the currently selected tool once, or by tapping an inactive tool twice.
You do have the ability to customize what tools are available in the quick access menu.
Whatever tool you select will remain on the sidebar unless you change the tool used. So you can select your most used tools and they will remain on the sidebar when you open other videos for analysis.
