It would be good to have a way to make sure certain kinds of queries are sent to Wolfram each time. For example, a query like "simplify 3x+1=x+2", which is a query that Wolfram parses without problem in the website[1], does not trigger the Wolfram widget right now, but if I could make sure that queries that start with "simplify" get sent to wolfram that would be nice.

Of course, I don't know how Kagi currently decides on whether to send a query to Wolfram or not so that's kind of hard to speculate about.
The way it works could be using regexes, if a match is detected then the current query is sent to the Wolfram api and the answer displayed in the widget (if any).
