While I still contend that I need to take items that I want to present (to various audiences) out of Aha and Notebooks and into Presentations such as Powerpoint and Prezi. In either case, exporting to a visual that can be imported or presenting in Notebook, We have very little control. To adjust fonts, colors, layout, cell size, page break, builds, highlights, animations, etc. etc. etc. If you want to use notebooks as the primary communication of this content. you must add more robust visualization and editing tools. Or let me better export the content to Tools that do the presentation as their primary role, and let Aha do what it does best -- manage the plan.
We have plans for major upgrades to our Notebooks to allow for greater flexibility. We've merged your idea into a larger one related to that update.
