Features

nearly all widgets have a N*XTSTEP look;
toggles can have an indicator in the left, telling if it's a checkbutton or a radiobutton;
a rough (better than nothing) implementation of auto-scrolling or menus that don't fit in the screen (like xfontsel);
menubuttons can have an indicator in the right, telling if it's a selection menu or an action menu;
scrollbar arrows can be removed through resources;
scrollbar behaves better when dragging the thumb and arrows have initial delay and repeat rate configurable,
includes a Clock widget (same of xclock, but with 3D border);
better internationalization, with support for character composition using dead-key.
