26 Safari vertical bookmark issues

How is it possible that your own bookmarks no longer open vertically but horizontally?

Now this group opens to the right, and you lose the complete overview of your bookmarks!

Please, Apple, it's great that you're incorporating this feature, but let users choose if they want it.

I personally work with bookmarks all day, and this new way of opening bookmarks takes much more time because I have to keep clicking back for an overview!

Please let us be able to click ">" to open the group vertically downwards.
