The settings in the language dialog only reflect the initial
language you will get when you next click execute, not the
current ones in the user's language.

That's a good idea. I'll do that.

Are you asking about adding your own new languages? I'm not sure that I
quite understand the question. Right now, when someone (typically
a tool, although there are a few languages built in to DrScheme
that aren't added by tools) adds a language they specify a list of
strings that stands for a path in a tree to the language. The first
elements of the list of strings are interior nodes in the tree
on the left-hand side of the language dialog and the last strings
are leaf nodes in that tree.
