The swap file saved my work a number of times. If you never use recover and use Vim regularly, then go ahead and disable it; if you haven't used it because you don't know how to use it or you only rarely use Vim, then I'd encourage you to either try it first or leave it enabled (as it is by default) until it becomes a nuisance.<p>And like u/strogonoff, I also disable line numbers, but that's just personal preference of course. For vim newbies, relative lines might also be worth checking out: "set relativenumber".<p>One thing that really annoys me is :Wq or :Q not being commands. Or typing only Q because you didn't hit the : and accidentally entering ex mode. Or hitting F1 instead of escape. I can recommend:<p><pre><code> command Wq wq
command WQ wq
command W w
command Q q
nnoremap Q <nop>
map <F1> <Esc>
imap <F1> <Esc>
</code></pre>
Or for the non-newbie that has the 'too many terminals' problem, "set title" will give your terminals more useful titles. There are a bunch more things, of course, but these are the lines in my vimrc that I think are useful to most people.
