Folks:
I'm totally getting Zav's concept of individual UI element states, like buttons, radio buttons, etc. What I was referring to is kind of a "meta-state". For example, with my slide show presenter analogy, one state might be:
state 1) no slide shows loaded.
--the first, next, prev buttons are disabled and the dropdown slide select menu is disabled.
state 2) slide show loaded and first slide is showing
--the first and prev btn are disabled, the next btn and slide select dropdown are enabled and the select dropdown has a marker at the first slide (the little marker that shows the selected line when the menu is opened).
state 3) slide show at a valid slide, but not at start or end
--all buttons enabled, slide select dropdown is enabled and a marker is at the showing slide.
etc, etc.
This approach would require the definition of larger application "states" that have sub-definitions, of each of the UI element states. So, it would look like a single UI element state, but that state would apply to the sub-states of individual buttons, checkboxes, menus, etc.
