I think it would be helpful to have language-level cheat sheets. For example, someone could search "Python cheat sheet" and get normal results, but on the side column there could be a prominant annotated cheat sheet. This is separate from the StackOverflow-sourced cheat sheets that show up now.
If you all are interested in doing that, I would strongly recommend using the cheat sheets from https://learnxinyminutes.com. They're licensed under CC-BY-SA, which should fit well with Kagi's business model. They're also community maintained and available for a ridiculous amount of languages - everything from Markdown to Kotlin to F# , with some related stuff like PCRE and Vim thrown in.
