Wasn't really used since it wasn't properly finished (no support in UI).
The idea of having ways to support defaults is good, but can probably be
done better in a different way. (I like the idea of a embedded second
ini file, which serves as 'default'. But many ways are possible).
AS usual, write support removed, read support still there for now.
