There's the new version of ShoreComponents with some new features 
including VisualWorks support, full window layout, new hideable panels, 
new lists etc.

See Wiki and RSS Feed at 
http://www.squeaksource.com/ShoreComponents.html for more details.

Demo at seasidehosting is not currently updated.

If you will contribute to this project, please keep VW compatibility in 
mind or use ShoreComponentsSqueak package with Squeak specific code and 
it will be ported to the crossplatfrom package later.
