RueLue: It should be possible to search the page history (the whole database? - for registered users only?) for a specific change of the page without opening 10 or 20 page versions or diffs. This is specially interesting for old pages with hundreds of edits. Attributions to discussions become torn apart or text has been added (same line) by other persons, but the text doesn't belong together and the sens sometimes got lost. So: search database for time, when a specific text has been added, changed or deleted.
This search becomes more difficult, if text has been moved from one page to another, or, worst, the original page has already been deleted. (see Message board, Entry of 07 October 2010 and 27 October 2010)
