But there's a feature that maybe some don't know: in addition to creating shelves, you can mark then as exclusive shelves, giving them the same behavior as the 3 default ones (Read, To-Read and Currently Reading). This week I finally decided to use a separate shelf to my TBR de facto, and another one for the books I stopped reading for a while but intend to return to it later. This is the result:
To do this, you only need to go to My Books and click on edit, on the right side of Bookshelves. Then mark it as exclusive and it's done!
