The 'Window' menu can be used to show and hide the panels in Actinic. Use this menu to select and de-select the panels to show, and click 'Window | Restore Initial Views' to put it back to the standard arrangement.
You can click on the title bar of any panel in Actinic and then drag it to another position on the screen. You will see the outline of the panel 'lock' to different positions. It takes a little bit of experimentation to get the screen exactly as you would like it, so here are a few tips:
· Use 'Window | Restore Initial View Layout' to undo any changes you make.
· Drag a panel onto the title bar of another panel to overlap them and create tabs.
