Ability to remove Wiki (page) history
I'm using Redmine Wikis in my projects and I appreciate their "history" feature, but there are some pages which are used as a notepads for further discussion about issues (think: RFCs) in which only the most recent version counts. Which brings us to a number of features I can think of:
- ability to mark Wiki page as non-versionable, ie. edits do not create new versions, they operate on the newest present (currently edited),
- ability to bulk delete whole Wiki page history (all versions without the most recent of course),
- ability to bulk delete whole Wiki history (just like above, but one button for the whole project Wiki).
