Thank you :)

Quickly wrote a partial wrapper around Wise; can I have your code now,
Hal? (forgotten right now whether it's hidden in this thread somewhere :)

Note: Wise makes any widget a top-level window if the parent==nil

Side note: I see patterns in the wrapper already, wasn't there some
proposal of a pre-initialize and post-initialize to be able to coordinate
super() within constructors more flexibly?

that's plausible, too ;)

I'll have to check the Rouge code again, as well.
