Thanks for submitting this!

I think after receiving several issues regarding the About Modal we might want to go with redesigning it for a longer term solution over implementing smaller fixes, so I'm going to close this for now. I'm sorry we weren't able to get this in, but please feel free to join in the megathread discussing the About Modal's design or check out other issues in this repository!
