I've made some updates to the Echo3 demo to show off the post-beta2 changes in the framework. The demo is available at the usual location, http://demo.nextapp.com/echo3csjs. New features include an entirely new rendering for the CalendarSelect, which now displays animated effects when selecting dates. WindowPanes and SplitPanes now offer rollover effects. The DropDownMenu renderer was given some aesthetic improvements as well. There's more to come before beta3 (notably in that TabPane will receive some significant updates), but things are progressing smoothly and beta3 is not too much farther out.
And for anyone interested, the echo3demo has a SVN repository, https://svn.nextapp.com/svn/echo3demo. This particular build can also be downloaded from http://download.nextapp.com/downloads/echo3csjs/3.0.beta2.1/echo3demo_3.....
Would appreciate any bug reports on the updated demo app (it's the first impression people will see of Echo3, so it's fairly important it work well).
