There are two types of browsers, single doucment interface (SDI) and multi-document interface (MDI). Both support files and web pages using GRML, CSV, and delimited formats.
The browser interface has three parts. The navigation area contains the navigation buttons and the address bar. The dockable area contains the toolbars and windows to support file and web browsing. The viewing area displays content using files and web pages.
The viewing area in SDI browsers has only one display window. With MDI browsers, there is a workspace to support multiple display windows.
