We are introducting a new Launcher tab in JupyterLab notebook sessions. When you open the Launcher tab, you'll see that each conda environment now has a unique button so that you can easily visually identify the conda environment that you want to use. The text below the button is the human friendly name of the environment. This replaced the slug name that was there. If you hover over the button, you can see the slug name.

The console section has been removed. When you click on a conda button, you can choose between creating a notebook or a console.

JupyterLab dark theme is now supported, as well as, changing the font size.
