Is it possible to display the Time Stamp of messages by default in both the Desktop Messages app, and the mobile app?
This is the default view:
Obviously, the time stamps are viewable by hovering the mouse over a message for the desktop version, or swiping left in the mobile app.
But having them always displayed without the mouseover popup like this:

Would make far more sense. There doesn't seem to be a setting to always show the time stamp in either Messages.App or Messages for iOS, and I'm aware this doesn't seem to be an Apple-supported option, but perhaps it would be achievable through Terminal or an add-in.
