I think that such a feature is absolutely necessary. The bitcointalk forum is growing and expanding, the number of participants is rising, and it becomes more difficult to follow the discussions of which you are a participant. "Show new replies to your posts" and "Show unread posts since last visit" don`t fully meet the requirements of forum members and don`t show quotes for previous posts. Given the number of topics and answers, it's easy to lose comments on your posts. I believe that the function of demonstrating quotes to the posts you have written will allow the participants of the forum to concentrate on the discussions that interest them and not to lose the thread of the conversation. Instead of writing superficial posts in a multitude of branches, forum members will be able to more deeply understand several issues of interest to them and will maintain a full-fledged conversation with those who have similar interests.
