Safari bookmarks layout changed and favorites missing

Yesterday I had all my favorite bookmarks and folders of bookmarks in a panel on the left side of the Safari window. Now all that is gone and "recently Saved" is there, something I do not use. Further, all the favorites were at the top, folders below, and the folders had a name only with no additional detail. How can I get back to that?
