Again, these are meant to be classes, not names.  The names that appear under
symbols should those of the commands.

And an 'option' locus should be made, instead of using 'converter'.

I should have a variable for setting the locus name, which can be different
from the class.

You're right, that is more OO than my code, which was kind of hack to begin
with.  It certainly would be the next step in windowlet development to make
those the changes.  Be my guest :-)
