How to make a simplified workspace for the Blender Video Sequence Editor
Since Shift+A will open the file add/import options and the render options are in a tab of it's own we can get rid of these from the VSE UI.
In order to collect all sidebar options(both Preview and Sequencer) in the same sidebar the Preview can be changed to Sequencer/Preview.
To have the playback options right under the preview like other NLEs the Timeline can be swapped with the Sequencer area.
A missing tab is Preview, the walkthrough also show how to add one of those and finally save the workspace as a default one.
