Hi Luis,

1) Unfortunately it's not possible to move the breadcrumbs below the featured image without doing some custom work which goes beyond the scope of support. You would either need to hire a developer to do it for you or add in your own code edits. We do offer a custom work service if that's any help at all?

Theme Customization

2) The top bar is hidden on smaller devices. To make it visible just add this CSS to Waxom > Advanced > Custom CSS Code box:

@media only screen and (max-width: 768px) {
#topbar {
    display: inherit;}
}

3) Yes the theme supports translation plugins such as qtranslate or WPML
