After Super Editor 2.0, a new workflow, Quick Mode, was added. This Mode can be thought of as separating the file into preview state and normal state.

Click the file to preview and double-click the file to open as in 1.x version. Remember, there is one and only one preview window, and the window is marked with "^".

If you click on a script and then double click on it, the preview window (the window marked with "^") will disappear, or if you just double click on a script, the preview window will not appear.

If you modify the file you are previewing, the preview window (the window marked with "^") also disappears, The normal window is displayed

If you right-click a preview window and select the Dock Tab, the preview window also disappears
