I feel like we need to put captions on projects (not just animations). I know I need them, and it would be great to have them for those that are deaf or hard of hearing. Not only that but you could set it for other languages in order to make it more accessible.
If you would like to get captions on animations (and other projects) - weather for yourself, or someone else, spread this around and get this seen. Like favorite and remix! Spread the word! https://scratch.mit.edu/discuss/topic/672558/?page=1#post-7086081
