CAS can be used as stand alone program and as MS Internet Explorer add on. Instants of Web pages, parts of Web pages, can be saved by one mouse click, with user highlighted parts. Thousands of images can be previewed with different speeds and selectively saved. Saved pages can be easily displayed in a parade, tracked, sorted by domains, categories, page marks, saving time .etc. Less important saved pages and links can be temporally hidden. Many Internet web pages (or instants of the same page) can be displayed at the same time. Though marking can be done before saving, you can remove, modify or add some marks in saved pages. For example in a web oriented message board discussion (forum, talkback .etc.), you can mark some parts in some messages or news articles to help you to elaborate your response you can also view all messages. Other special functions, like saving multiple images, caching or saving similar links, are available.
