OK.  I think that's a great idea, and it should not be too hard to
implement.  You will need to provide a GUI for editing, but this is easy
with gtksourceview.

You also need a way to save and load the user's code.  If you are
targeting Sugar 0.84+, then the easiest way to do this is to add the
programmable tools to the datastore object's metadata as a string.  See,
for example,

http://wiki.laptop.org/go/Sugar.activity.activity#How_do_I_implement_a_write_file_method_for_my_activity_in_order_to_persist_my_activity_in_the_journal.3F

This method is very easy to use (probably one or two lines of code) and
has the advantages that (1) it only creates a single Journal entry, and
(2) the Journal entry it creates is still a standard PNG file, so it
retains excellent compatibility.  However, this method will only work
reliably on Sugar 0.84 and newer.
