Settings -> User Interface -> Show the bookmarks bar

I installed Opera 20 and the first thing i noticed is that many useful features are missing:

• Opening new tab on middle click

• Opening new private tab from right click menu

• Missing "recently closed pages" from top right corner

• Missing bottom tab with zoom slider

• Missing customization options for speed dial (size, number of rows, removal of [+] button ...)

Why remove them?
Maybe I'm missing something and if I do - please tell.
