i find it strange that there is no option to provide feedback that isn't positive so I'm just using the uncategorised section.

I think gamma is VERY good at creating new slide decks from scratch and giving people inspiration, but it is currently very very very bad at improving existing slide decks. I tried several times to give it some very basic and well structured powerpoints and what it returned was comically bad. For example, in one slide it turned our small company logo that was originally on the top left into a giant image that was warped and stretched out across the entire slide and then dropped all the text in the slide unformatted in front of it. Each slide was also a different format. Using it to improve our slides was our main use case as a business and it was a rather embarrassing demonstration - as a result our CEO has ditched the idea completely.
