click-through casacading menu
A click-through cascading menu allows you to pop the cascaded menu directly underneath the cursor, making it available for immediate use. You'll find you can get to 2nd and even 3rd level cascased menuitems remarkably quickly.
Cascading menus are an excellent way to organize and group actions within an application. They allow users to establish a visual roadmap to the various functional bits and pieces of an app, and they allow designers to arrange things in useful hierarchies. However, they're not so great to use due to the amount of mouse travel necessary to walk through the successive menus, and this inefficiency is paid out continuously once the user is familiar with the roadmap. Argh.
Additionally the click-through cascade nicely allows traditionally cascaded menus as well.

non-lossy visual design
Visual design which allows movement of individual visual elements without loss of context. While specific elements come in and out of view, the context retains its shape so that the bigger picture is not lost or compromised. The commonly termed "pan and scan" techniques represent the visual opposite, i.e. lossy visual design.

time-release button
A button which releases a menu if mouse-up is not received within the configured time. Otherwise, it takes immediate action on mouse-up. The most-common action is assigned to the immediate action of the button; related but less-commonly used actions are placed in the menu. A time release button appears as a usual button on mouse enter,

but on mouse down presents a gradient underscore

to indicate "hold for more available actions".
