I like that it is easy to integrate with other services, such as GitHub Pages or Netlify CMS/CDN integrations are useful too! There isn't much you can do without using their service but they have some really nice features built in by default if needed (eCommerce integration).
Not enough documentation about how everything works behind scenes so there's room of improvement here unfortunately - maybe more tutorials? It would be great when users don’t need any technical knowledge at all because then everyone could benefit from this technology easily since people usually hate learning new stuffs especially things related coding languages etc..
