Is it possible to change the extension position(by modifying the extension.js) in gnome-shell status area? I mean that I'd like to see the language indicator in the first position(from left to right), cuz it's visually easier to find it.
Using information from this page we can deduce that you need to change the line in the extension.js that says
Main.panel.addToStatusArea([sometext], [othertext], 1)
After modifying the extension.js file, hit Alt+F2 and then put 'r' in the box and hit enter.
