[REQ] please improve macOS client's UI

ok, guess there are priorities in app development, but frankly, comparing the desktop (MacOS) UI to the one of other IM platforms, it must be said that Jami doesn’t shine by its esthetics : no background decor like in WhatsApp and other IM apps, speech bubble colors are washed out and not very compelling etc…
Maybe the team should simply hire a UI guy and brush the UI up to some higher standards?
