ok I have understood, thank you for the details by email
you must switch again to the "editor mode" to update the content into the editor, then you can save the left panel

Thanks for the confimation, I already knew I have to switch to the editor to make it stick.

My point is that I shouldn't have to do that, I mean, CK could pick the textarea content no matter the state of the editor.

I'm saying this, because I already know that this happens, and not only it forces me to do an extra click, but also if I forget to change it back to the editor, I will lose every change!
