Answered How would one go about showing a SQL query result in the Manager?

I've got a client who has a simple form collecting data in a custom (non-modx) table - it simply collects 'How did you hear about us' inputs from the main contact form.

I was wondering what the best way of retrieving this data and displaying it somewhere on the Manager would be?

Create my own extra? Can I create a 'page' that appears in Manager and uses a Snippet to echo the result?

Any advice is appreciated!

Many thanks!
