I had a ridiculously fine tuned neovim setup in my dotfiles that I created over the years, including a nice neovim terminal setup that I can navigate/change using only keyboard (never been a big tmux fan). I've managed to replicate some of it decently with VSCode (vim extension, and I can do CTRL+j to open a terminal and CTRL+k to move back to the editor), but it's just slow and has a tendency of crashing at the worst time.
