I once thought of the following, which is related to what you suggest here:

Is it feasible/desirable to build a debugger for LOGO using LOGO (e.g MW)?

If yes, will this facilitate the teaching? A while ago, while I used
MicroWorlds
1.0, I thought maybe I could use a series of textboxes to hold Logo
instructions
and then wrote a simple interpreter that interprets (runs) the instructions
in these textboxes one by one. A turtle in the shape of pointer would point
to
each textbox as each instruction is eveluated(MW's run command). Values
of variables are shown on the screen as sliders or textboxes. The student
can push a "step" button to cause the interpreter to execute one LOGO
instruction, and the instruction pointer (a turtle) is pointed to the
textbox
containing the next LOGO instruction, and the interpreter pauses,
waiting for the next "step" pushbutton command from the user.

One thing I find a little bit strange is although we the youngsters a pretty
real
programming language (Logo), their development environment seems to
be not as good as the "real" development environment. Kid's development
environment should not be as complex as adult's. But I think some features
(e.g. the sigle step feature, and the variable display panel) might be
useful for
youngsters also. Are these features provided by MW 2.0? BTW, I should
mention that my son and I like MW very much. Their reference manual and
"How-to"  guide in MW 1.0 (I do not know much about 2.03) are very good.
