I tried to setup a layer stack by using layer names instead of gds numbers as described in the help page. I have layer names with colons to specify the datatype.
13/0 -> metal1:drawing
But it is not possible to reference to layer names which includes a colon. Maybe this can be fixed in a new klayout version?
I tried escaping with backslash but I get an error (red input field).
