Whenever we go through a person's (actor, screenwriter, director) list of works, we only see if the drama/movie has been added to our list or not. The problem is that we don't immediately see if these are works that we completed/dropped/on hold/plan to watch. It becomes necessary then to check each drama to see what our status for them is.
I propose to change the "pencil" button to different icons that would immediately show which among a person's repertoire were completed or not. This would help people like me who've watched a lot of dramas immediately see if I still have dramas on hold for a certain actor (whenever I go to their page) or if the dramas I added are ones I was able to complete.
