Submit screenshots of all your *NIX desktops, themes, and nifty configurations, or submit anything else that will make themers happy. Maybe a server running on an Amiga, or a Thinkpad signed by Bjarne Stroustrup? Show the world how pretty your computer can be!
Not OP, but it looks like they are using texlab for completion: https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#texlab
Apart from that there is https://github.com/lervag/vimtex with file type support, document compilation, etc. For grammar checking I use https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#ltex and for snippets https://github.com/L3MON4D3/LuaSnip. See https://github.com/iurimateus/luasnip-latex-snippets.nvim for latex snippets and what you can do with them.
