In Logos on my desktop Windows machine, I have a small 'R" icon in the sidebar that shows a list of books when I click on it. Right clicking on items says they are in a folder called 'reading'. I can remove items from the list by right-clicking on them, but I have not figured out how to add items to this list. It contains a different list of books from the "read later" list on my iPhone. I like the simplicity of this list over reading plans, but only if I can figure out how to manage this list.
