You can see recent changes hierarchically below a particular page as follows. Make sure to copy from the edit screen instead of from the displayed page because [] stuff isn't displaying correctly.

Add the following method to the ZWikiPage class:

def get_flat_offspring_page_names(self, REQUEST=None):
    """Return a flat list of all my offspring page names."""
    myid = self.id()
    nesting = WikiNesting(self.aq_parent)
    return nesting.get_flat_offspring_page_names([myid])

<hr>Also add this method to the ZWikiPage class:

def get_flat_offspring_pages_sorted_by_mod_time(self, REQUEST=None):
    """Return a flat list of all my offspring pages sorted by modification time."""
    pages = []
    for pname in self.get_flat_offspring_page_names():
        pages.append(getattr(self,pname))
    pages.sort(lambda p1, p2: cmp(p1.bobobase_modification_time().ISO(), p2.bobobase_modification_time().ISO()))
    pages.reverse()
    return pages

<hr>Finally, add the following method to the WikiNesting? class:

def get_flat_offspring_page_names(self, pages, did=None):
    """Return flat list showing all offspring of a list of wiki pagenames.
    did is used for recursion, to prune already elaborated pages."""
    if did is None: did = {}
    flat_list = []
    for p in pages:
        been_there = did.has_key(p)
        did[p] = None
        if not been_there:
            flat_list.append(p)
            if self.childmap.has_key(p):
                children = self.childmap[p]
                if children:
                    for p2 in self.get_flat_offspring_page_names(children, did=did):
                        flat_list.append(p2)
    return flat_list

<hr>Now you can set up a very simple RecentChangesBySubject? ZWikiPage as follows

<form method="GET" action="RecentChangesBySubject">
Enter a page name to see all pages below it in the table of contents sorted by modification time.
<p>
<b>Page:</b> <input name="subject" type="text" size="30">
<input type="submit" name="submit" value="See Recent Changes">
</form>
<p>
<dtml-if "_.has_key('subject')">
<dtml-if "_.has_key(subject)">
<dtml-var "subject"> pages, most recently changed first (you may bookmark this URL for future reference).<p>
<dtml-call "REQUEST.set('the_page', _.getitem(subject))">
<dtml-call "REQUEST.set('the_offspring_pages_sorted_by_mod_time', the_page.get_flat_offspring_pages_sorted_by_mod_time())">

<table border="0">
<tr><td><b>Page</b></td><td><b>Size</b></td><td><b>Last modified</b></td></tr>

<dtml-in "the_offspring_pages_sorted_by_mod_time">
<tr><td>
[<dtml-var "_.getitem('sequence-item').id()">]
</td><td align="right">
<dtml-var "_.getitem('sequence-item').getSize()">
</td><td>
<dtml-var "_.getitem('sequence-item').bobobase_modification_time()">
</td></tr>
<dtml-if sequence-end>
</table>
<p>(<dtml-var sequence-number> pages)
</dtml-if>
</dtml-in>
<dtml-else>
<dtml-if "subject != ''">
There is no <dtml-var "subject"> page
</dtml-if>
</dtml-if>
</dtml-if>

<hr>You can put hyperinks to this page (with the appropriate parameter set) on the standard header by adding this code to standard_wiki_header:

<p align="right"> <small>
   <a href="<dtml-var wiki_page_url>/map"> Entire table of contents</a>
   - <a href="<dtml-var wiki_page_url>/offspring"> <dtml-var id> contents</a>
   - <a href="&dtml-wiki_base_url;/RecentChangesBySubject?subject=<dtml-var id>"> <dtml-var id> Recent Changes</a>
      </small>
