Sure.. basically you want to do something like this..
/cms/templates/Includes/CMSMain_right.ss
<h1>$ApplicationName</h1>
<div class="dashboard-module">
<h3>Recent Page Updates</h3>
<ul>
<% control RecentUpdates %>
<li>$LastEdited : $Title</li>
<% end_control %>
</ul>
</div>
<div class="dashboard-module">
<h3>Recent Uploads</h3>
<ul>
<% control RecentUploads %>
<li>$LastEdited : $Filename</li>
<% end_control %>
</ul>
</div>
/cms/code/LeftAndMain.php
public function RecentUpdates()
{
return DataObject::get("SiteTree",null,"LastEdited DESC",null,10);
}
public function RecentUploads()
{
return DataObject::get("File",null,"LastEdited DESC",null,10);
}
You get the idea..
