Hello,
Ok, great.
1) Do you want to change the styles according to our demo? You can change main styles here http://prntscr.com/gqs4gg
If you need more changes provide me temporary admin panel access.
2) The top bar is hidden on mobile devices. You can add one more switcher into Mobile Sidebar widget area.
3) Footer languages also have styles panel http://prntscr.com/gqs5vc Also, you can use custom CSS area to change the styles according to necessary design http://prntscr.com/gqs6mn
