Recipes in concrete metric units, preferably mass instead of volume. Recipes come together incredibly quickly when measuring out ingredients can just be dump-tare-dump-tare-dump instead of trying to get sticky ingredients like tahini out of a measuring cup.
More torx screws. There are apparently some uses for phillips, but torx are criminally underused.
I would add that all recipes must use the common professional standard format with ingredients and their amount at the top, preferably alongside the required equipment followed by the estimated prep time and cook time followed by the consecutive step-by-step listed instructions.
My brother was getting one of meal subscriptions akin to Blue Apron and there was never any rhyme or reason to the format, content, or layout of the included recipe instructions. -An egregious oversight.
I also have heard that when torx heads become stripped they turn into hex heads. I've never investigated this claim, though.
