Keep in mind though that sometimes they're not 100% accurate; some stories that have been completed for years still have the open book icon, and some stories that are still on-going have the closed book icon.
Oh so I have to open and see after all!!
Atleast you realised the icon. Good job i say. It will definitely save some of your time while you're in a rush
I made this account in 2020....I realised this today....
Haha.poor you. Guess the hunger to read something delicious really been making you go blind. Jkjk
True actually
It took me years to realise there is a book icon in front of each title here that denotes 'completed' or 'incompleted'
