Don't be shy! People actually USING the software I make is the fuel I
need to keep developing it actively!
This is why I'm rewriting osgWidget. Not NEARLY enough people use it, so
the current version is a failure as far as I'm concerned. I am smarter
man now however, and the second version will be far more appropriate for
OSG. Plus, I'm going to have LOTS of time here coming up where I'll be
"bubble boy" and have nothing else better to do than hack on code and
keep my mind occupied.
