The desktop uses the GTK toolkit, like the GNOME and Xfce desktops. The design focuses on small, simple programs using drag-and-drop to move data between them. For example, a user might load a compressed file into a spreadsheet from the web by dragging the data from the web browser to the archiver, and from there into the spreadsheet. A program would be installed in the same way, by dragging the archive from the web to the archiver, and from there to the applications directory in the filer.
