Different Layouts Not Loading JS

Ok, that is it.
I have A LOT of elements etc. and a number of projects to work on. Is there a recommended way to do this that might expedite things?

I’ve been using this JS by @stephen to make my projects responsive. Proportionally scaling a Tumult Hype document based on the browser width

In your opinion do you think it would be important to change over and use the built in Hype responsive features?

Thank you!
