Some things would be improved with more attention to accessibility. Ext.tree.TreePanel, for instance, allows keyboard navigation out of the box. In a similar vein, the results grid doesn't allow row selection/keyboard navigation (ref. Ext.grid.RowSelectionModel).

JMVC doesn't provide packaged widgets (though it is starting to). It's about providing a middle layer (above jQuery, less than customizable widgets) to build customized apps that are as light as possible.
