In a content page's diff, there is a link to the page of the editing user and a link to edit an old revision and save it as the current. On flow page diffs they're missing.
Here a compare of features within content page diffs, flow diffs and the history of those page types
| Feature | Content page | Flow page | ||
|---|---|---|---|---|
| Diff | Hist | Diff | Hist | |
| Edit an old revision | Yes | No | No | No |
| revert | Yes | Yes | unknown | |
| undo | Yes | Yes | Yes | Yes |
| links to user page | Yes | Yes | No | Yes |
| comperation of chosen revisions | Yes | = | Only neighbours | = |
There should be more features. The most useful would be the link to userpage and "edit an old revision". This would be more comfortable.
