Autosave on notes and replies

It would be super useful if there is an autosave feature as we are typing in the reply or writing a note. Currently we can start writing a note, move to work on another ticket and come back to pick up where we left off. However, all the content of the note/reply would be lost if we experience sudden power outage or if we logged out. This would increase efficiency since some replies take some time and additional research to come back to.
