In regard to Web Accessibility (according to WCAG and Section 508) it would be nice if deleting an image description would still leave an empty/null alt tag on the image. Currently if you delete an image description it deletes the alt tag entirely and this causes accessibility errors when conducting audits.
Images used for presentation purposes should not have a description but they still should have an empty alt tag so WCAG audits do not show errors. Some websites have to pass these compliance tests regardless of whether it actually impacts the end user in a negative way.
Also, I know this is way off Surreal’s focus, but for a long term vision, maybe think about connecting APIs for web standards, SEO, accessibility and broken links. This would add a lot of value to Surreal. Or maybe something as simple as linking out to third-party checkers.
