A while ago I made GroupMe Analysis, which is a bot that you can add to your group, and then see interesting facts about it, including number of comments, likes, and a person-by-person breakdown. However, I couldn't find any tool to download an entire GroupMe that wasn't just making a CSV file or something boring...

I made a Classily.js plugin for elegant class toggling. Simple yet powerful, it can solve complex tasks when used correctly.
