Missing 'Go to Parent folder' feature Rated 4 out of 5 stars

I am using this add-on already more than a year.
I would like to treat ScapBook as Bookmarks.
For bookmarks there is an add on called "Go Parent Folder" (https://addons.mozilla.org/en-US/firefox/addon/go-parent-folder/). It is very handy with all-in-One addon.

The same functionality (filder and go to parent folder) would be very handful in Scapbook too.

Here are some image to illustrate, what I mean.

This review is for a previous version of the add-on (1.5.6).
