My nvim setup
Nvim, being a terminal application is great at being minimal and bloatless. Being in the terminal means no GUI bloat which is really good at improvig general speed like bootup and opening.
Vim excels at being keyboard only which means your hands never leave the keyboard increasing efficiency. Nvim's reliance on fast and simple key combinations also increases efficiency. Who need the scroll wheel up and down a page when you can just j,k,gg, and G.
Nvim is like a clean canvas, simple and barebones at the start but very malleable to your liking.
