Zoom into slide to use it as canvas
It should be possible to use a PowerPoint Slide as big canvas and then zoom into it (as an animation) to go more into detail of an object or section. This would be extremly useful combined with (more complex) diagrams / graphics (like SmartArt) to visualize (complicated) structures in a clearer (and cooler) way. Similar to Prezi, but PowerPoint should use both techniques (slides and canvas, in the form that slides are still the main elements but you can use a slide as canvas where it makes sense) and combine their advantages.

Check out PowerPoint Zoom, available in Office 365 Editions of PowerPoint:
If you want to use an entire slide as a canvas, just right click the slide, copy, paste as picture on a blank slide. Copy slide and on new slide, enlarge to where you want, click transition/morph. PPT does the rest. You can then just copy the enlarged slide and move to your next element - morph will already be there, so again, ppt does the rest. You can do the same thing with just copy and pasting elements to new slides and using morph.
You can do this with office 365 which now has a Morph transition fx which works really well
Yes, like PPTPLEX!!!!! Bring it back!
