We have taxonomy term pages that are used as landing pages on our site fully fleshed out with components and our client content authors need ability to preview these terms as they would for nodes. Any entity type that has a route really should allow for preview.
Add/Edit any entity type other than node, no preview options in config to generate preview button.
Add preview button configuration to other entity config forms and generate preview button on add/edit forms.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Other entity types for preview doesn't seem like a realistic thing without some considerable core refactoring that appears to be distant. Closing this out as its clearly out of scope of what Gatsby module can accommodate any time soon.
