I use the tabbed mode, so all windows are tabbed. With the font size set to zero, the tab bar is so small, that it hardly takes up any space, but can be used with a stylus. With your fingers, you can use the program switcher bundled with penguinphone ("alttab", click on the top right icon on the statusbar) to switch tasks.

Works well for me


EDIT:


Here are two programs open + the task switcher. You can see the tab bar below the status bar (the blue tab is open).
