A quirk I have is I don't like it when IDEs interface with my version control system. That is MY version control system. Don't touch my stuff, IDEs
But! I have another quirk, which is that I don't like git, and I use Mercurial for everything
And the quirks cancel each other out! I check my projects out in Mercurial, which is obscure, so IDEs don't support it, so their VCS integration fails and I am happy
