One of my big slide puzzles is usually a messy table of pros/cons of a product, or a competitive comparison. How to highlight the right dimensions. Make sure that one is not a sub point of another. Make sure that cells have short text in them. Make sure that text is roughly equally long in each cell.
GPT-5 is very good at this. Copy-paste the messy table into the interface, and the output is pretty useful. Something to integrate in SlideMagic at some stage.
