Over the past four months, I've been using Omnigraffle as my go-to diagramming app. During that time, I've collected a small set of tricks that make wireframing and diagramming easier.

If you're a grizzled 'graffle veteran or someone who reads manuals, some of these might be old hat. But maybe not – so check them out. If you've got any of your own, post them in the comments.

RT @Folletto: Smart Objects in Omnigraffle: how to.
It's an awesome hidden feature for Omnigraffle Masters!
