In version 0.50.X, a new tab model was introduced that allows jumping between files. However, in Jupyter Notebooks, it does not work properly — it suggests navigating to the raw .ipynb file’s section, which is obviously not possible while working inside Jupyter.
This is a serious design flaw that should be addressed. Moreover, overall .ipynb support in Cursor is absolutely poor. You should definitely pay more attention to it.
Thank you.
