Jupyter Lab - launches but don't see any tabs (look/feel is 100% different than seen in youtube videos)

I could not find an answer to this issue on Windows when searching Stackoverflow/Google/Bing, and this thread was quite prominent hence my Windows-specific answer here.

CTRL+SHIFT+ENTER did not work for me. On windows 10 with Jupyter 4.4.0, Jupyter Lab 0.35.4, the tabs in Jupyter Lab can be made visible/hidden by clicking CTRL+SHIFT+D or toggling in the menu the options (View > Single-document mode).

Jupiter Lab, menu item for toggling the Single-document mode


Just pressing Ctrl+Shift+Enter can toggle showing the tabs on/off. Often one tends to press by mistake and see it disappear


I updated my browser to Chromium Version 56.0.2924.87 (64-bit). The prior version was Version 43.0.2357.130 (64-bit).

On the new version of Chromium, the Jupyter Lab works as expected.

I wanted to answer this question so any other users who experience something similar have a document resource to find a solution.
