Nautilus bookmark settings
To manage bookmarks go to the Files menu in the panel to open the Bookmarks dialog. There we may enter a name and a path of a bookmark to appear in the Nautilus left side panel in the Bookmarks section:
Bookmark an opened directory
Alternatively open the directory you want to bookmark. Then click on the cogwheel top right to select "Bookmark this Location" or press Ctrl + D.
To remove a bookmark select "Remove"" from the right click context menu on the bookmark.
All our bookmarks will also be displayed as a quicklist:

Those bookmarks are stored in an editable file in
.config/gtk-3.0/bookmarks where we may manually (or programmatically) add and remove path entries which take effect immediately. The examples above resulted in the following file content:
file:///home/takkat/Documents/My%20Bookmark My Bookmark
