Hello,
I’ve been working on a TUI Jupyter client called euporie, which I’d like to share with the community.
It includes a notebook editor, which provides a similar interface to Jupyter Lab or Jupyter Notebook, and a terminal console, akin to Jupyter Console.
It features rich output support (Images / HTML / LaTeX), and (partial) support for ipywidgets.
It’s really useful in situations such as when you SSH into a remote server, or are working in a docker container, and don’t want to or can’t set up port-forwarding to run Jupyter Lab. Or you might just prefer working in the terminal 
Let me know what you think!
