Auto-save for messages

I have lost HOURS if not DAYS of work because guest messages or property description copy or any other typed work is not being saved as you type and all it takes is an update, a notification, or popping into another window to lose all your work. Every basic chat/message app since 1994 has had the option to save the copy, or does so automatically. Please add this feature as an IMMEDIATE PRIORITY. I have been asking for years.
