To add the equivalent of a 'Like' button to the Wiki Activity page on a per-edit basis. For this to also be represented on a page's History in the same way. Ideally to be able to have a Comment option too, expandable when clicked.
This is for communication to editors about their edits. Supporting with praise and discussing the reason for changes otherwise.
The current Comments are useful for discussing the content on an article, rather than individual edits, which is why they wouldn't be as appropriate.
@Tupka217 I have looked and there isn't anything like that there.
@Fan26 I don't disagree, but if it's an optional feature for a wiki that can be turned on/off, then whether it's suitable for a wiki can be determined by the admins of a given wiki. An increase in social interaction can be a good thing for a team, especially if its optional.
