Canned queries are very useful to direct users to prepared data and views. I like to use them with charts using datasette-vega a lot, because people get a direct impression at first glance.

datasette-vega doesn't show up by default though, and users have to click through to it. Also, datasette-vega does not always guess the best way to render columns correctly though, so it would be nice if I could specify a URL fragment in my canned queries to make sure people see what I want them to see.

My current workaround is to include a fragement link in description_html and ask people to reload the page, like here, which is a bit hacky.
