Well, we can give you general tips on how to implement the
changes but you are going to have to actually go into the
code and get it working.

For example, that "Editor is read-only" can be done by setting
the -state option of the editor's text widget to disabled.
You would need to add a command like:

$text configure -state disabled

The "reverse video" thing should not be hard at all. Just
set the background to black and the fg to green. Here
is a quick wish (Tk) script to get you started.

$ wish
% text .t -bg black -fg green
% pack .t

The docs have some info about each of the format strings
you can use for an "External Editor".
