Certainly. Your links sit on a "desktop" in Netsso each with different themes. You can decide to give each link its own icon and in that case each desktop will probably take 60+ links. Or you can create a sub-group on a desktop, giving it a title and an icon, and then create links without icons under that sub group title. In that case you'll fit c. 80+ links on a desktop.
Also, you can move links, with or without icons around your desktop, by simple "drag and drop" and you can move them between desktops via the right-click context menus.
