The idea to me is simple, but I'm sure someone will tell me this has either been thought of or it isn't possible.
We are all familiar with iOS' Copy/Paste Call Out menu, but how hard would it be to build a small extension to the end with the camera icon? When this is pressed, it will drop you into your Photos and allow you to attach a photo natively while in the mail program, instead of copying the image prior to attempting to reply.
Is this even a possibility or does it already exist? I hate not being able to reply to work emails and send a photo reply in line with the email without going out of the way to do it.
