What's the con of the LSP? I'm not familiar with the concept, it sounds like LSP is running in a separate process (which honestly sounds good to sandbox plugins, though I could see it being problematic, I wouldn't be surprised if in practice it functions better to most "integrated" language plugins in other editors.) As far as tmux I'm a heavy emacs user but honestly I use it mostly as a text editor, I use a separate terminal emulator almost always. So lacking tmux... not something I would notice. Relearning my Emacs muscle memory is the most daunting thing, but I could probably be convinced for a fast editor written in rust with good defaults.
