A discussion at GitHub has all the details here https://github.com/gatsbyjs/gatsby/discussions/31842 and originally here https://github.com/gatsbyjs/gatsby/discussions/30735#discussioncomment-757061 Basically it would allow for better control over client caches and CDN caches to control how often functions are called and cache leading to improved handling of quota.

Notifications for build/deploy success/failure work really well. The only missing bit is the Build Started notification. (Maybe Deploy Started as well?) Having this, it would be really easy to implement build indicators for different CMS. I know something already exists for the Preview. But from our experience clients are more interested to see the main website status.

Having the web UI as the sole interface for configuring a large number of sites is just painful. Headless Gatsby Cloud, no ?

Many environment variables hold the same value for build and for preview. Still, the configuration needs to be manually duplicated and kept in sync. It is my suggestion to have processing logic so that in preview, the value of a build environment variable is used when the matching environment variable in preview is missing (unspecified).

I setup a site of mine before the bitbucket integration was complete and would love to see a way to change the source without having to create a new site

It might already be exposed but it's not documented. Useful for plugins that use the commit SHA for release tagging.

I'd like an option to automatically cancel builds triggered by merges to the main branch if there are no changes in the working directory. Very important for monorepos and multiple sites. Currently 80%+ of my builds are unnecessary. (Comparable feature: Netlify "Ignore Builds")

Currently, users are limited to 5,000 redirects when adding a site to Gatsby Cloud. We should allow unlimited redirects for sites hosted in Gatsby Cloud though this may include some performance hits as the redirects file grows.

We have clients that will be editing a page in the CMS and wish to preview but occasionally the preview will break and we have no idea, it would be great to be notified when a preview stops working.

If you try to preview on a mobile device, the overlay gets in the way of the content.
