I’d like to suggest in the WME a switch (perhaps in the user control panel) for downgrading the own editor level.

For example:
If I’m a level 5 Editor, but only want to edit simple streets which are only on level 1, i can switch my own editor level to something lower than 5 for this action. This would prevent myself for accidental editing more important street e.g. highways.
Compare this with an account in the IT… Even if I am an administrator… I shouldn’t be logged in always as an admin but just as a normal user with rights just for my actions.

An other example:
Some tools, edits and so on are only available for higher levels of editing. To support a newbie with level 1 or 2 I should be able to switch also to this level to offer more or better support.
