Allow editors to mark revisions as "hidden" and add hide those revisions in article history page by default. This functionality could be used to hide vandalism from the edit history.


Users with the appropriate permission can set and remove 'hidden flag' on revisions. The delegation of this authority can be decided by individual wikis and may be assigned to pre-existing groups or a new group may be created. Hidden (un)flagging are logged like other activities, and accessible on a per-user or per article basis.

By default, 'hidden' revisions are not shown on the history page. Instead, a button similar to 'there are 22 hidden revisions (show)' is displayed. Access to hidden revisions would always be provided even to anonymous users. Registered users could set a user preference to un-hide by default.


Currently the edit history of popular articles is almost unusable. There's no reliable way to distinguish between major edits, typo fixes, vandalism and spam and the sheer number of vandalism makes it tudious to browse throughout the history for useful edits.

The proposed mechanism would allow people to participate in quality improvement in small bits, without the need to deal with complexities of the whole system and would encourage them in further and deeper participation.
