how to create a new folder
You used to be able to add a new folder by picking "new folder" and then add the name of the folder. Now when I want a new folder, that choice is not there. When I want to move a new folder, all I had to do was hit move to and a menu would appear of previous folders. And you had a chance to save a new folder if that was your wish, or scroll down and find a folder is already there. Now I do not have that choice to start a new folder.

You can do a Copy/Cut and Paste in the right-click context menu to move a bookmark. If you have a bookmarked page open in a tab then click the highlighted star to edit this bookmark.
The "Edit This Bookmark" dialog that opens if you click the highlighted star has a checkbox with "Show editor when saving" (shortcut key in the dialog is Alt+S). This item is at the bottom just above "Remove Bookmark" and "Done".
