Is the LSP support in nvim better than what you can get with plugins? I'm using coc.nvim with vim and yeah it is really cool.

I didn't know about that :term difference. I think I prefer vim's behavior there.

If you have :set hidden, then the current buffer will be hidden when you open a different file, and you won't be prompted. Without it, vim doesn't allow hidden buffers and will discard the buffer when you open a different file (which is why it prompts you). Vim's defaults are very odd sometimes.

Huh, that cw behavior in vi does seem pretty jarring. Interesting, though. It makes sense why it was like that.
