Total Commander

I now got the new Galaxy Nexus.
Total Commander is my favourite "explorer" on PC and Android! Thank you for that!

But on my new Android 4.0 I can't copy any file out of the system folders because there is always the error "access denied". Could you please fix that?

BTW:
Could you add the possiblity to the editor to get root access? It is really annouying to copy a file to the sd card, edit it and copy back

Are you sure you rooted your Galaxy Nexus? TC (or any root file manager) cannot acquire su permissions if the device is not rooted.
Do other root applications work correctly?

It's also possible that the device is missing the commands like "ls" to list directories, or "cp" to copy files in root mode.

Try it with a new button, type "root command", with command
ls /data
or
ls -l /data

so geht es nicht.
it does not work.

There must be a space after "ls":
ls<space>/data
ls<space>-s<space>/data
