#159) Header icons should be easy to understand at first glance
Two out of IKEA’s three icons are confusing.
On desktop it’s possible to add alternate text which shows when hovering the mouse on the icon, but not on mobile. So I think a better approach is to not use confusing icons in the first place by not deviating too much from standard icons for important features. For a shopping list for example, which I view as a Wish List, you could use a heart icon.
