What is the single version of MultiView?

I'm trying to create a new filetype that does not have the splitpane feature and the view tabs. I can't find a SingleView or similar.

Not checking the MultiView in the FileType wizard seems to remove the UI completely, which isn't what I want either.

I found out how to remove the source tab, but the visual tab remains even tho it is the only one.
I understand, that MultiView has the splitpane by default, is there no way to disable it?

I've checked out the source from netbeans in hope of finding something useful, but 4GB is a lot of sourcecode to look through.

I started looking at the Image Module, but it doesn't seem to be up to date with the api and uses a lot more code for the basic setup.

Any alternatives?
