Indentation for every variation level that is not inline, for second and third level of variations or the number set in preferences for variations not inline. Each new level of a variation is moved a little to the right and on a new line just like first level of variation. And main line should not continue/follow right after a variation but resume on a new line. Each variation should resume from the same indentation it's been started that implies to resume on a new line.
excellent idea. has any work been done on this feature request? thanks :)
