A project is a playlist with all the songs, videos, presentations and other elements for your meeting. To add a new element you can drag it from the drawer, or drag a media file from the computer directly. Drag elements inside the project to rearrange them.
To navigate between elements you can click them or press the arrow down/up buttons on the keyboard.
Click the button in the bottom of the project area to add a new section. Here you can add titles for reference in your playlist, and add lots of notes.
Press any letter key on your keyboard when nothing else is in focus to start searching in the drawer, and press enter to quickly add it to the current project.
