Keyboard layout indicator in gnome

It has been discussed several times. This question is just to get the latest answer from the experts.

Is it still impossible to get a keyboard layout indicator in the top panel in gnome shell?

My personal experience says, it is impossible. I can use keyboard layout indicator in gnome classic, ubuntu, xfce, lxde! But not in gnome shell.

Also, will it still be impossible to use it even after release of ubuntu 13.04?

For whatever it is worth, I think it is quite strange and sad that what can be done in practically every other DE can not be done in gnome.

If you mean something like this (Ubuntu 13.04 Gnome Remix):

The indication change when you switch layout with your selected keyboard switch combination.

I installed the AppIndicator extension (https://extensions.gnome.org/extension/615/appindicator-support/ ) and then, after the first change of keyboard layout, you have a keyboard-layout notification in the gnome notification zone. Open ubuntu tweaks, extensions, select AppIndicator options:

and be sure to select "show in panel" for the keyboard indicator.

Hope this helps, Romano
