Right, so you want eMacs evil mode with some choice vim plugins. Excellent vim emulation. The terminal interface is pretty good, and the GUI version has some excellent markdown plugins that give you a live preview. Get started with doom-emacs as it’s very pro vim and modernised out of the box. Then once you’ve got into eMacs you’ll not have any issues with free time ever again, as everything you could possibly want to do you’ll be doomed to finding out how to do in eMacs.
