Currently, elements such as text, boxes and hover boxes don’t adjust to column width and overlap when the page is resized. If you added the option to stretch these elements, they could adapt to the width of columns and create truly responsive websites.

Yep, yep. Good points 
I think wix is cooking up some magic. Time will only tell!
Yeah I hope so. Funnily enough they already have this functionality in the editor. If I add or remove a column the boxes inside will automatically adjust, but unfortunately not the content inside the hover boxes.
It would also help if we could add horizontal margins, like with strips. It would stop the content feeling so crammed with when viewed on a tablet.
You can avoid this by reducing the width of your content but then it feels too spaced out when viewed in a browser.
