序列编辑器 & 预览
Some users prefer working in this view because all the tools are available. On the other hand, the toolbar and Sidebar occupy the whole screen and so, it is not possible to have the Sequencer timeline full width without also hiding the Sidebar and Toolbar for the preview and vice versa.
And of course, it’s also not possible to have the Sequencer timeline or the Preview alone in fullscreen (Ctrl-Spacebar); eventually on a second monitor.
