Even if they are for "wicket's internal use", documentation might be
valuable, especially for (wicketstuff) developers who go deeper then regular
users. Furthermore, having some basic JS utilities (with documented public
API) coming with Wicket would make using Wicket even more fun. I'd bet that
a lot of Wicket users implemented Wicket.$('id') or something similar on
their own. And I'm not talking about a fully fledged JS framework or
library, just some basic stuff to handle common tasks like the whole event
stuff or some DOM manipulations. Basically just what's in place already but
kept secret for "internal use only".
Maybe that's a candidate for the Wicket 1.5 wishlist ...
