I just have a few plugins which help. Mainly the LSP for gotodef and popovers for type info, etc. This was what finally made me transition to neovim. Also a tree viewer, Startify, and :Rg for ripgrep integration. Those are my big ones.
Sadly my workflow of using `!` to get back to my terminal and things like `!make` or `!cargo build` is fucked in neovim. So I do a lot of ctrl-z and the a lot of killing stopped processes I forgot I suspended. I've complained about this in various threads and chats, but the developers aren't interested in letting us use the old vim `!` which is super lame.
