Hey Sara,
I’m sorry to say that I had to shut it down. Knack raised their prices to a level that I couldn’t afford any more, while providing “find” for free.
I have built a free Chrome Extension instead, can be found here: https://forums.knack.com/t/knack-track-chrome-extension-available-for-classic-builder/19888 which basically provides the same info.
If you have any questions about this extension, or ideas on how to improve it I’d be happy to help 
Thank you
Nir
