Answer: 
Click on "Carpeta Personal", create your Work file in Home (or wherever you want). Then right-click that new file and left click on Bookmark (or for you it's probably "Marcador" or something like that). Then it should be available on the left-hand panel.

You can drag and drop the folder too. Just look for the cursor to have a green plus sign and a line to appear indicating where in the list the folder will appear.
