You will notice I have been making several changes lately with comments and replies. First with making the replies collapsable and now with adding reactions. There will be some more changes to comments and replies coming that I am working on. I just wanted to let you know that for now while I am making these changes, I am only applying them to homepage and profile comments. I want to get everything working just right on those 2 sections. After that, the plan is to roll out these changes to every other comment and reply section of the site, like blogs, images, fan fiction, reviews, etc... So eventually you will have all of these features like reactions everywhere you can comment.
