(I prefer the previously identified route of getting preview for updates and then edit histories).
I'm curious about this....
I certainly appreciate having the preview button available when creating a node, and I miss it when when updating.
I tried a [id://Super Search] on "previewing updates" which turned up nothing. Is there a separate discussion on this elsewhere, or plans to implement it?
Comment on Re^4: The ability to delete (self reap)
Sorry, I don't have a ready pointer to a node on this subject nor a good lead on a quick way to find one.
One reason for preview is to reduce the number of changes that get logged. I suspect that additional tricks will be required to reduce the resource requirements for logging changes to a reasonable level, though. We already have previews (and change logging) for other types of updates.
