Quick tabs or buttons with pre-made or custom one line responses. When a text comes in but it isn't a good time to responds a tab that opens to a quick list of one line responses like "I'm in a meeting text in a little bit" or "I'm driving give me a little bit" and allow for someone to make their own like "I'm on the toilet" or " Honey I'll get back to you in a little bit. " You could have "getting ready for work" or "on my way home" , or even "f- -k off" the ability to add 1 or more floating tabs or buttons(colored or not) and place them anywhere on the screen of an open text. different responses in different locations top left, top right, bottom left, etc etc. And all you have to do is press the button 1 or more times (a safety to prevent butt sent text would be to press same button multiple times to send) and pre-made text would be sent with a sound verification that it was sent so you wouldn't have to take your eyes off what your doing.
