Joel Webber : "We've had a lot of ideas for new widgets and libraries banging around in our heads for a while, and I think it's about time we started really building out the UI library. To this end, I'd like to propose a set of potential Widgets and simple frameworks that will give GWT apps much more leverage in building good interfaces : Color Palette, Inline Text Edit, Slideshow, Decorated panels, Collapser , Progress bar & busy indicators, Tag clouds, Value Spinner, Link List, Sliders, Dueling Listboxes, Image map, Image Button, Image Strip, Toolbar, Vector Graphics, Rich Text, Fast Table, Splitter Panels, ComboBox, Date & Time Pickers, Effects, Drag & Drop, Custom tool-tips, Data Binding and Form Validation, Good default CSS, Consistent selectability, Ubiquitous keyboard support, TabBar Needs Widgets, Printing support.
