improve nav behavior - remove hamburger on desktop, on mobile move hamburger to toolbar #32
Description
Desktop:
- There is no need for a hamburger icon on desktop - it's a distraction!
Mobile:
- LW has 2 nav menus - hamburger and bottom toolbar.
- Let's streamline into one menu.
- Move the hamburger icon from header to the bottom toolbar.
- Bottom toolbar is better reachable and can directly expose most-used menu items.
- Moving hamburger to toolbar makes space for the whole Progress Forum logo in header.
- Menu icon from https://heroicons.com - menu-alt-2
