I love Neovim. It's been my main editor for years now. The way it handles terminal sessions is so much better than vanilla Vim. Also LSP rocks.
What do you mean by "terminal sessions"? I use vim inside regular xterms or tmux. Am I using such terminal sessions already? What would be different in nvim?
One thing i do use it for: In neovim there's options to open the terminal as a sort of overlay on top of the existing splits, they call it floating term. Its really nice for opening tools ( e.g. lazygit or a test runner) because find it a bit less disruptive than having to bounce in and out of the editor by other means.
