While I like the new library "Filter" function in Logos 8, I'm missing a function that existed in Logos 7: in Logos 7, it was possible to set the library to showing only books with, e.g., a 3-star rating. This setting would remain after closing and reopening Logos. In Logos 8, we have to set such a filter for every new search in the library.
I liked this function in Logos 7 and organized my library based on it: I gave books 3 stars if they should always be included in a library search and 2 stars if they should only be included when I (temporarily) removed the filter. So, I would like to see this function back in Logos 8.
