@Daniel_Weikert it depends. A lot of people like Jupyter notebooks because they can combine explorations with developing code. Often they then are faced with the prospect of isolation the ‚productive‘ code from the other stuff in order to bring it into modules or .PY files and so on.
With the use of Tags (and distilling the code into functions/modules) you could in theory have a Jupyter notebook that contains both exploration and productive code and just run the productive tags in KNIME. If this does make any sense very much depends on your way of doing stuff and maybe the state of your project - I personally like using KNIME to develop workflows and then instantly bring them into production (leaving the exploration in another workflow in a workflow group) - there also would be integrated deployment as a similar concept to the tagging in the Jupyter notebook.
As it is so often with KNIME: it can be done. If and how you use it is up to you
