I wish the old formatting toolbar was still available because:

1. The old formatting toolbar was much faster for changing the cell styles because it listed all the styles without using a scrollbar. There is also a delay probably due to the style previews.

2. It was just one click to change the text alignment. Now you need to click a tiny arrow first.

3. It was was possible to change the cell alignment of output cells.

The new default toolbar seem great for new users but not so much for experienced users that already know most of the keystrokes for the buttons in the new toolbar. I wonder what is the opinion of other users on this...

The formatting toolbar was made obsolete by the new default toolbar and has been deprecated.

though Help system includes it?

Sounds like the docs hadn't been updated, I'll look into getting it updated.
