@adis737 Since these pages require user authentication, the implemented navigation will only lead users to login page which of no use

[adis737]

Yes, but pomodoro and contributers page can be accessed as usual and other pages need authentication which is suitable, as before there were no options to navigate to these pages. It also makes the homepage more interactable.
