    Define WORK-IN-PROGRESS file type with Obsidian-style front matter
    
    This does not work yet for common actions like renaming the file based
    on its front matter. I will continue testing how viable this is and if
    it is worth pursuing. I do not want to make the code more complex to
    accommodate this use-case, so let's see how it goes.
