User Review Limit

No and it would require quite a bit of modification to the rate_review architecture in order to allow multiple reviews by the same person on a given item. They can edit their review and change the all the content for that review (to include the main rating). This was recently enhanced.

 

Feel free to suggest it, however, I can already tell you, this wouldn't be something added to the XF 1.x version of Showcase. Its a MAJOR architecture change and that just is NOT happening in a 2nd point release.

The only thing I'd consider adding during a 2nd release is "updated" functionality (so you could edit an older review and "update" it which could change the rate/review date to current OR instead of date change, add "updated" to the sorting type for reviews OR a combo of both). That kind of stuff doesn't require major architecture changes to pull off.

Its not a "built in limitation", its standard unique architecture. Both the Core XenForo XFRM and XFMG have this same unique rating architecture (which is a common industry standard).

 

No, that would require custom development.

 

Users can EDIT their reviews now, however, it doesn't store HISTORY. Core XenForo does have a History Handler, but its meant for MODERATORS to be able to revert changes made to a SINGLE field (like the message field of a post). Implementing History on a Review would only handle 1 field eg, the Summary field.

Nothing is stopping them from adding text to there edited review saying they changed it from 4 stars to 3 stars.
