I would like to add a new tab next to the existing tabs in jupyter notebook. I did a lot of research and I always come back to nbextensions. However, those extensions provide changes within a notebook. I wrote code (in PyCharm) that does some computations with given files. I want to implement the same code within the jupyter notebook environment by adding a tab to the menu (see image) and when the user clicks on the tab there will be an interface with more options and functions. Can someone help me with this?
Something like the nbgrader extension is also good. When clicking on the tab a new window appears.
