You kidding?? Sliders is the only practical way to achieve a desired exact zoom level. Every other control has fixed size increments, while sliders have continuous zoom with instant feedback. This is not just 'nice to have', is a killer feature. I personally consider every zooming interface that lacks a slider a failure, unless one of these conditions is present: - the application only supports semantic zooming, so there aren't any intermediate continuous levels. - the zooming range is too narrow for a slider to matter - a few clicks can get you through maximum to minimum. - there's too few space available for a slider to fit in the interface and thus exact refinement must be sacrificed. _______________________________________________ usability mailing list [email protected] http://mail.gnome.org/mailman/listinfo/usability
