This is similar to an option on my native messaging app on Android. The mightytext option should be on PC and Android

I assume there is no one monitoring this topic. Too bad. This loss of feature has stopped be from using this, and instead I am using MySMS since it has a signature file option.
Adding a signature line would help. I use text in my business and it is essential to identify myself
How about it picks up your signature from your phone?
How can i add my signature
