Dude,I get what you’re saying…but what I don’t get is how often you need to say it.
Björn’s not going to do it. Easy as that,really…
So if you REALLY need widgets,I’d get myself a book on Erlang,
and a couple of books on graphics programming,
and just make that plug yourself 
For as long as Wings is open source,you’re free to do what you want with it.
Or,you could try what someone did at the official forums…
Can’t remember the name,but a user offered $500 for a plug to be developed,
an exporter to rwx format I think it was,and it WAS developed by someone.
Or,just use it without the manips…I think it works REALLY well without them myself.
