Normally, the working directory of a notebook is its parent directory. So if I create a notebook ~/projects/abcd/eda/nb1.ipynb, then the working directory for nb1.ipynb will be ~/projects/abcd/eda.
I started Jupyter Lab in ~/projects/abcd. I want the default working directory of all notebooks to be ~/projects/abcd. Is it possible to achieve this? Ideally it should be something I can either attach to each notebook itself, or something I can set on Jupyter Lab upon startup, so that if someone else needs to use my project, they will be able to benefit from the same behavior.
I am OK with solutions that focus specifically on IPykernel, but a solution that works for all kernels (IRKernel, IJulia, Xeus, etc) would be best.
