Rightjs Core

1) http://rightjs.org/tutorials/assignments-and-chains -
"element.hightlight();" in the first listing, should be highlight

2) http://rightjs.org/tutorials/ajax-handling -
"Xhr.onSend(call_that_function)" - shouldn't that be onCreate/onRequest? Because above that it says that Xhrs send only
'create', 'request', 'complete', 'success' and 'cancel' events (BTW, looks like 'failure' is missing)

3) On the download page, where it says there is the main module and
old browsers module, it should be explicitly said which browsers are
regarded old - so that I can decide whether I want to support them at
all, or not.

4) Custom build page - there should be some info (tooltip, title attr,
etc.) on the entries in the list, that says in general what this entry
is about (e.g. basic/additional visual effects - which are those?
(Yeah, I can look elsewhere in the documentation, but it would be good to have that info right there). "form additional features" - what's
that? will I need that or not?)
