[Wish/Suggestion] Grouping conversation list, too many and messy conversations

First of all, thank you for your hard work, teacher! Since I enjoy trying out cards and am reluctant to delete topics from conversations that have too many, there are many conversations in the list that are temporarily inactive or repeated. I would like to have a grouping feature to categorize similar types of conversations, so I don’t have to search for too long.
