@Birthe sent me a pm with a working example - and I must admit that I also imported Jeremy's edited shadow tiddler..
Problem solved - and I'm sorry about the unnecessary "noise" ....

I am still left in the dark - when it comes to how you create a theme from scratch... I wonder if it's possible to create a "base-theme" - maybe the Vanilla theme *is* the base theme? or if any active theme might function as a base for creating a user theme which can be exported to other TWs as a plugin/theme when it has been combined in Tinka?
I don't feel quite comfortable importing all tiddlers from a "pretty involved" theme - adding a few of my own stylesheet changes - and call it "MyTheme" when it is in fact based on a full theme with another name.
I do understand that I could mark my new theme as "dependent on 'themeName'" (as Punch does with Vanilla) - and try to remember to import both themes (my stylesheet changes + the theme it is a customization of) - however I think that it would be nice to be able to collect a few base modules and your own changes made on top of those and create a theme with no dependencies which you could give a name and call your own creation.
Tinka gives us this oppertunity - however I'm not too keen on creating/rolling out new themes (or plugins for that matter) where most of the material included is in fact the finished/standalone work of somebody else....
Don't know if this makes any sense?
Maybe I'm just overwhelmed by the sheer amount of work (time) that has to be put into/spent on testing what parts of the Vanilla theme is absolutely necessary to be able to build a theme "from scratch" ... Don't know..
