This program is a great viewer for pdf-files. I appreciate that it uses multiple cores on smp systems, which is especially helpful when viewing files containing many large bitmaps. However, it is inconvenient that preloading is limited to 10 pages only. I therefore suggest implementing the option of setting this value much higher. It should be noted that it might be helpful to let preloading work in the background and stop if necessary to complete other tasks.
This program is a great
