[plt-scheme] custom widgets in mred

Close to my heart too; given most widget toolkits seem to lack the richness
one needs.

It's good to look at examples;

possibly hierlist.ss in drscheme

the various DrScheme XML and comment boxes as well as graph.ss is
interesting too, if you are prepared to think of snips on a canvas (sprites
roughly) as custom widgets

MrEd Designer includes some custom widgets that may be worth looking at;

(I don't know if they will survive in working form into v3.99->4)

Cheers,

Stephen
