probably the single most useful thing in NeoVim is :set inccommand=nosplit This lets you see the results of commands (like complex regex for example) while you type them. For me this has made a huge difference to the enjoyment of refactoring code. It is both possible and fun to try a ridiculous regular expression with lots of capture groups or even one that works across newlines when I can watch the results as I type. Saddly this only works in NeoVim to my knowledge, not in regular vim, but it's pretty amazing.
