While we are on the topic of figure previews, what do people think of using *nice* on the gs processes? My machine gets really bogged for several minutes when I open my thesis... When you have lots of figures to preview, this would make a big difference.
Another alternative would be to render the preview when the figure is exposed on screen for the first time (or for extra points, render the preview when the part of the document visible in the window is getting close to the position of the figure). There isn't really any need to render most of the figure previews in my thesis when I'm only working on one part of it. Ben.
