Behavior

• Each extra should provide its own palette.
• All created book extras should be listed in the Book Extras palette.
  • there must be either visual marker or label that shows whether the extra is visible or not
• Book extras should support drag and drop
  • drag extra from the file system to Sophie should import the extra
  • drag extra from Sophie to the fike system should export the extra

Existing book extras

• Stickies
  • Stickies should support text styling (these depend highly on text).
    • Bold (Ctrl/Command + B)
    • Italic (Ctrl/Command + I)
    • Underline (Ctrl/Command + U)
    • These are to be decided whether we should support them when the text is pasted into the sticky
      • Striketrough
      • Text color
      • Background color
      • Font
  • Stickies should provide copy/paste functionality for text with style.
  • Stickies must be listed in the stikies' palette (at the moment this palette contains only one button and its pointless).
  • A couple of predefined colors changing with one click (because of the styled text yellow maybe not so good for some cases).
  • Stickies halos must be with similar styling to the rest of the application (now the icons, look like from other application).

Import and export of book extras

• Probably it is a good idea the book to has some id that is used by the book extras
  • At the moment each time the user saves the book ref is changed and the stickies are no more associated to that book.
• Some problems that may emerge
  • (Stickies related) When page is deleted and book extra (sticky set is imported) the stickies corresponding to the missing page shouldn't be displayed.

Possible future book extras

• Bookmarks (similar to the ones in .pdf files)
  • Something like a quicklinks that the user can create for easier navigation within the book.
• Highlights
  • These were planned originally for Sophie 2.0. They give the readers possibility to highlight certain text pasages.
• Media (audio and/or video) annotations
  • Similar to the stickies but instead of a text they contain video or audio that the reader want to place somewhere in the book.
• Additional frames added by the users but not part of the book (like a whole book page)
  • Sample use case: Book containing some Problems which solutions are more complex and contain graphics.
• (not so sure about these)
  • Correction vizualization
  • Spyglass
    • Something like a frame that zooms only the content behind it. An accessability feature that may come handy to some users with eye problems.
