Kagi Redirects are a nice tool, but frankly confusing for their implementation. As Kagi expands to a wider audience, which will in all likelihood be less-tech-savvy than the current users, I think it would make sense to have somehow simpler implantation of redirects.
This could a library of 10 pre-built suggestions that can be added with just a click.
Or some version of AI to suggest the correct syntax and help users avoid asterisks, parentheses, hyphens, etc, which for many simply don't make sense.
Users could roll down the list of pre-suggested redirects and click "add" all at once. Or select the ones that are relevant to them.
Or even have a library of redirects with a voting system which allows the most useful ones to float to the top.
