I've released version 1.0 of the Save Layer Settings Archicad Add-On.
Support for AC27 was added last week and now there's also a Version with a German interface available.
Otherwise the Add-On is already running stable for a while.
The basic functionality can be accessed in a free version of the Add-On.

Archicad 27
You can use the Pro Version of the Add-On for free in AC 27 until end of October
(The AC 27 - Technology Preview Program ends on 20th October).
