Folder Editing slip reports where the folder can be seen

Users can create up to 12 folders visible everywhere and 12 more folders specific to each application. The system does not permit an application-specific folder to have the same name as a folder that is visible everywhere.

Folder Tab

If a view has a Filing button (for filing the view’s data into folders), then the view must also have a folder tab at the top so users can see the data they have filed in folders. A folder tab looks like the cut tab part of a paper file folder. The Newton folder tab shows the name of the folder whose data is currently displayed in the view. The name begins with a diamond because tapping it pops up a picker from which a user can choose which folder to see. Additionally, a user can choose to see only items not filed in any folder or items from all folders (including unfiled items). A check mark appears next to the current choice. Figure 8-18 shows a sample folder tab and picker.

Every Folder picker includes two choices in addition to the alphabetical list of folders. At the top of the Folder picker, above a separator line, is the choice Unfiled Items. At the bottom of the alphabetical list of folders, below a separator line, is the choice All Items. In both of these choices, your application can replace the word Items with the name of the type of item displayed in the view.

The Apple II is a defining product in the history of personal computing, first introduced in 1977 by Apple Computer, Inc. Designed by Steve Wozniak, the Apple II was one of the first highly successful mass-produced microcomputer products and played a significant role in bringing personal computers into homes and schools.

One of the Apple II's standout features was its color graphics capability. It was one of the first personal computers to provide color output, thanks to its built-in video interface. The initial model supported a resolution of 280x192 pixels with a palette of 6 colors, which allowed for vibrant visuals that set it apart from contemporaries like the monochrome Altair 8800.

The Apple II was notable for its open architecture. This design allowed users to expand the computer's capabilities easily through a series of expansion slots. Users could add floppy disk drives, additional memory, and various peripheral devices, making the system highly adaptable to individual needs. This encouraged a thriving ecosystem of third-party hardware and software, which contributed to its popularity.

Another significant feature was its use of the 6502 microprocessor. This 8-bit CPU was not only affordable but also powerful for its time, allowing the Apple II to run various applications efficiently. Along with a built-in keyboard and an innovative plastic case that housed its components, the design was user-friendly and appealing.

The Apple II also introduced the concept of “bootable software” through the use of floppy disks. The disk operating system (DOS) allowed users to store and run multiple programs without having to reload software manually, providing a level of convenience that had not been widely available before. Key software like VisiCalc, the first spreadsheet program, helped boost sales, showcasing the Apple II's utility in business and education environments.

The computer was also well-known for its early adoption of BASIC programming language. Apple provided an operating system that supported Applesoft BASIC, which enabled users, including students, to write their programs, further fostering a community of developers.

In summary, the Apple II's color graphics, open architecture, powerful 6502 processor, innovative use of floppy disks, and support for BASIC programming made it a revolutionary product in its time. Its legacy laid the groundwork for future personal computers and established Apple as a leader in the burgeoning tech industry. The Apple II remains an iconic symbol of the early personal computing era, reflecting a generation's transition into a digitally connected world.
