But omnigraffle is not designed for slides, it's for diagrams. Does it have slides features, like presenter's notes that will be displayed only on one screen ?
Does it have animations ?
Nope. If you want those, indeed, you'll need a different app.
PowerPoint-style animations are rarely helpful, in my experience. Either the animation is a pointless distraction, in which case you are better off without it; or the animation is necessary to convey the content, in which case no slide tool would suffice and you are better off with a video or a purpose-built vector animation (perhaps an interactive one).
