Treeview for functionlist

Feature request
  • Is it possible to become a treeview for the functionlist that we can drag and drop files better together for an easier overview?

    As an example the actual view:

    Main
    Sitename
    Sitename_login
    Sitename_count
    Sitename_check

    Example how it could looks like:

    Main
    -Sitename
    Sitename_login
    Sitename_count
    Sitename_check

    So the - is clickable to expand.
