I can't believe, given how often I've had to reinstall Omnigraffle, I haven't yet talked about the icon stencil I always use. OK without further ado, here it is; my favorite UX Omnigraffle stencils.
Webalys Icons - Using placeholders for icons is annoying when you have a good idea about what you want, but don't want to spend the time creating it to get your point across. Especially given the fact that crisp, flat, and modern icons have evolved to become symbols.
Webalys offers a generous icon pack for free as .ai, .eps, .pdf, and through, Omnigraffle .graffle. Hope it's useful. Download 'em here.
