Users should be able to easily rearrange their own website, within reason. Perhaps widgets could be classified as sidebar, homepage, etc. and then toggled on or off at leisure. They should be able to be dragged into different arrangements, toggled on or off, or even just display at certain times.
I would also love to see the ability to add new product carousels and arrage as you please.
Would love to see the ability to customize your layout and look more similar to Wix
Examples of sidebar widgets to toggle/rearrange:
Social media links
Twitch links
Image/banner links
Calendar
Examples of homepage widgets to toggle/rearrange:
Featured products/collections
"Deal of the day" or "on sale" collections (potentially with an automatic timer)
Integrated blog

New Products releases/banners
