Fwd: feature suggestion for editing config files.

  I have an idea of smart file editing. While editing configuration files, an
editor could give information about a field of file, which is currently active
(cursor is in place of the field). This is like tooltips in Windows, but gives 
more
information. Information could be in a separate window or at last row of editor
window. information would be presented as long as cursor is located in the 
field.
Editor could also give advice about value ranges and errors in field values.
If editor knows different file formats, it can also autocorrect typing errors
in text fields.
