Please add more options to reading status other than Completed and Reading such as Series Dropped, Plan to Read or On Hold along with an option to update the number of chapter currently read so it's easier to come back to a series and directly pick up from the last chapter read.
For NU? Do you mean status in Country of origin on the main page or in your personal reading lists? If the latter it’s possible to make more, just click edit lists while looking at any of your reading lists to open the page for making more. You can add all sorts of lists. I usually switch which list a novel is on with the quick add feature on the novel page itself. I believe this may be off by default. I hope it helps!!!
