Background

Unlike a command line operating system or CUI like UNIX or MS-DOS, GUI operating systems are much easier to learn and use because commands do not need memorized. Additionally, users do not need to know any programming languages. Because of their ease of use, GUI operating systems have become the dominant operating system today's end-users.

Early Graphical Desktop Environments

A GUI uses windows, icons, and menus to carry out commands, such as opening, deleting, and moving files. Although many GUI operating systems are with a mouse, the keyboard can also be utilized by using keyboard shortcuts or arrow keys.

5. Linear browsing can be activated by using "Go-Film-strip" menu item in the Study Place on a selected heading or sub heading.

Zero Point

Zero Point means that a place from where you can reach every other place. At the end of installation process of NotJustBrowsing a structure is built to represent Zero Point for user's computer. This structure will allow a user to access most of the operating system's functionality from within this structure. At the same time it will provide a structured way to store/access the information that builds up with time in every computer.

Information, may it be local (on user's computer) or on world wide web, can be referenced in one unique way using NotJustBrowsing.

A user will now be able to access all places and facilities present on their computer at one time by using either "linear" or "multiple" or both views.

Elements of Zero Point

Picture below is the Zero Point location. From this location you should be able to access all functionality provided within your computer.
