ServiceHolder is perfect for internet users who have a large list of favorite sites and who need an organizational system with which they can find and access them at any time. Also, it is capable to block some areas of these sites that contain annoying banners or toolbars. It enables you to load several pages at the same time without consuming many of your system resources or crashing your computer. If that is not enough, it allows you to connect its layout with Microsoft Internet Explorer and export your list of favorite sites from there. It's compatible with Windows OS.
