I think you should either make the quotation marks ('"') work at least as well
as in Java or make the editor just do what I type. Making them _somewhat_ clever
is pretty annoying.

Type "aaa" then delete the last ", type it again you get "aaa"".

More complex: I am trying to write a String that contains:
  I say: "Hi!", you say "Bye!".  
I have to escape the " so it will look like:
  "I say: \"Hi!\", you say \"Bye!\"."
I start typing "I say|" - so far so good. When I have "I say: \|" and I press "
it does not add anything. I type on to "I say: \"Hi\| now I type " and it will
add "". In short, typing every odd " at the end of string literal will be
ignored, every even " will be added twice.
