1. Can we avoid a hamburger icon and show navigation as is?
2. If not, what icon do we choose to indicate navigation?
3. Are the icon and padding large enough for comfortable tapping?
4. Will we place the icon on top left/right, bottom left/right, or floating?

6. What exactly happens when the user clicks/taps on the icon?
7. How will the icon change on tap or click?
8. Will navigation appear as full page/partial overlay, accordion, or slide-in?
9. If we use slide-in, does navigation appear above or below the header?
10. Will we have some sort of animation or transition on click?
11. Can we use just CSS for the animation to stay performant?
12. What if the user opens search/filters and drawer at the same time?
13. Do we expose some critical navigation by default on desktop/mobile?

15. If search is placed within the hamburger nav, can we pull it out?
16. Do we need to add a label ('Menu') or replace the icon with the label?
17. Can we use the 'less/more' pattern to display at least some nav items?
18. Can we use tabs or a scrolling pane to expose some sections of the site?
19. When do we start hiding the hamburger and start showing nav items instead?
20. What if we have space to show some navigation items but not all of them?
21. Do we want to show/hide navigation on scroll down/up?
22. What metrics do we use to measure how well our navigation performs?
23. Have we tested how the hamburger performs against other options?
