A single Timeline panel appears in a frame in the lower central portion of the screen when you first launch Adobe Premiere Pro, open any of its default workspaces, or create a project. You can remove all sequences from a Timeline panel, or add multiple sequences to it, each appearing as a tab within that Timeline panel. You can also open multiple Timeline panels, each within its own frame, with each containing any number of sequences.
