The tab content in My Templates: Content, Section, Global Widget, Header, Footer, Single, Archive, are not translatable. Could you add gettext support to them?

By the way, I did find a whole bunch of non-translation-ready text throughout the Elementor/Elementor Pro, and wrote myself a script to update them on every update. If you guys are interested in maximizing i18n support, I could post all my findings here for you to fix them officially.
