Another bug / feature....
Using the source version of the ArcGIS Viewer with the config-all.xml configuration.
a) There appears to be no way to close a 'headless' widget once it has been opened.
[INDENT]Would it be better intutaive if when you clicked on the icon in the widget container for a second time that it closed the widget???[/INDENT]
b) Changing <widgetcontainer layout="horizontal|float|vertical|fix"> from horizontal to vertical appears to have no affect - although I may have done something wrong.
Otherwise a step in the right direction!
