Thanks. Do you remember what was amazing? I've been using a fairly vanilla JupyterLab setup as the basis for a (proprietary) project. I've found the docs generally OK for what I've been doing.
To be honest one of the worst things about JupyterLab I've found is the number of interesting extensions that look great but turn out to be unmaintained or overlap with others. It can be really confusing!
Basically, we build a lot of internal webapps and it's so common that you need to compare x against y, go back and forth between screens...
Most users simply open up multiple tabs and view side by side.
To me, if we could easily have the interface setup so that every object opens in a new "window" with the ability to dock side by side/navigate independently, I just feel it is much neater than the standard admin templates we use on a daily basis.
Truthfully, I've not spent ages looking in to this, but, I did spend a few hours with the Jupyterlabs code and I just got nowhere.
Basically, I would love to just get a page up, the full Jupyter interface, standard menu bar to the left or on top and the ability to just load multiple "Hello World" pages in separate windows.
