When apps have native look and feel, they have consistent behaviour, affordances and accessibility: - buttons are labeled and placed correctly, and respond to expected input (including secondary focus and secondary action on MacOS, for example) - dropdowns/selects behave correctly, and respond to expected input (for example, you can type to select in MacOS dropdowns). - windows have OS-defined areas for drag/resize, for titles, for toolbars etc. They also appear correctly in the OS's window management tools (app switchers etc.) - text inputs use the OS-default shortcuts and have access to OS-provided tools (e.g. spell checker) - controls and windows respond correctly to keyboard and mouse. E.g. for a while Apple's own Catalyst apps didn't have the standard Cmd+Q to close the app. Many custom modals do not dismiss the modal on Escape - context menus are standard in the places where you expect standard context menus. Well, app menus, too. And the list just goes on and on.
