She always said how interested she was in product development. It would have been great to watch her develop some of her own recipes through trial and error etc, making her own dairy free/vegan versions of things, etc. I know she says she's not a big cook and more of a baker but even that could be a challenge for her to try 100 new recipes or something. I love the videos where she eats like X for a day.
While I love Grace and I do think her videos are often well thought out and have a lot more creativity to them than a lot of other Youtubers it would have been great to see something different.
Didn't realise I had so much to say on the matter so I'll stop here
