The main window has three resizable columns — Video, Control, and Audio — whose widths are remembered between launches.
- Video column: the list of imported video clips, with grid, list and filmstrip views.
- Control column: playback settings, transitions, video export, external display selection, language, and license status.
- Audio column: the list of background music tracks and their playback settings.
- Bottom bar: start/stop and pause/resume buttons for playback.
