ссылки я смотрел, даже читал кое что, хотя честно скажу в английском не очень сил╦н, мануал ещ╦ какой нибудь почитать меня хватит, а на остальное терпения не хватает , насколько я понял у тебя с английским дела обстоят намного лучше, вот почитай:
"Opera has pioneered many new features later copied by more mainstream browsers. For example, Opera was the first browser to integrate mouse gestures as an easier way to navigate pages. Opera also has several other original features, including multiple document browsing (as well as the more limited tabbed browsing), background loading of pages, batch opening of bookmark folders, fast forward and rewind functions which predict where you would surf next, notes, skins, and session management..."
"...Opera became famous (and somewhat notorious) for its MDI; that is, all browser windows were opened in the same parent window. A taskbar was later (version 3?) introduced to make managing them easier. Version 6.0 brought a major philosophical change for Opera, with the addition of a single document interface (SDI) Mode. Ironically, this happened when many other browsers, like Mozilla and Galeon, started using a tabbed document interface (different from MDI in that it isn't multiple actual windows). Opera 6.0 gave the user the choice to use either MDI, SDI or tabbed mode and became thereby the first browser to support all three modes."
