Bookmark Toolbar is very inconvenient for users who have a lot of bookmarks, because:
1 - In the toolbar fit just a few bookmarks, and horizontal scrolling is impractical.
2 - Toolbar take away space in height, which is at modern wide-screen monitors are always too low (due to more comfortable reading entire A4 documents and the like.)
3 - Opera's bookmark system does not allow importing bookmarks from other browsers (eg. From Firefox or Outlook)
These deficiencies are for many users with a lot Bookmark sufficient reason to renounce the use of the Opera, which is otherwise extremely lovable and good browser. Therefore, FOR EACH RECOMMENDATION IS (with Toolbar that can be also removed) TO INSTALLING THE SIDEBAR STRIP WITH BOOKMARK - LIST (modeled on the Firefox) WITH THE POSSIBILITY OF IMPORTS FROM MOZILLA AND OUTLOOK. The Bookmark-Toolbar should show the first ten bookmarks from the list, with the possibility of (temporary) removal from the site.
Sidebar list is more suitable than current solutions, because modern monitors have plenty of place across the width, and the Sidebar-list does not cover the content of the browser.
