CYS: Update patterns/color/fonts only if the user clicks on "Save"

[gigitux]

UPDATE:
We want to remove the Save button within each section and change the label of the Done button to Save.

Regarding the issue above, I'm wondering what the point of the Save button is because even if the user didn't save, the selected pattern is still visible on the site when returning back.

@gigitux, I agree. I believe it's because we're still dragging a pending decision on Woo Express, where we thought of removing the "Save" button completely. Thanks for flagging it 🙏 Let's revisit the behavior and update the pattern/layout/colors/fonts only if the user clicks on "Save" as per your suggestion. Thank you 🙇‍♀️
