I think textra needs an away message, not only can you switch it on if you are in class or sleeping etc... but also if you are just feeling anti-social. "Hey, I know I'm posting to social media, but I'm exhausted from human interaction. I still love you, but I'll get back to you in 3-5 business days." That just seems a lot nicer than ignoring someone.

I know you have a drive mode one, but I really think this is helpful!
