Hi Niek,
Yes it is. Although it is not a configuration variable, you can - without too much hassle - easily change this behavior manually. Open up /admin/index.php and look for the following lines (approx line 50).
// Open recordset for sites' pages
$result
= mysql_query("SELECT * FROM pages ORDER BY `published`, `menu_id`, `toplevel` ASC, `sublevel` ASC", $link);
$total_rows = mysql_num_rows($result);
Here you see how the list is ordered. First by publication status, then the menu id, etc. To get it by pagename I suggest you first keep the published, then replace menu_id, toplevel and sublevel by `urlpage` ASC (ascending from A to Z or DESC for Z to A)
Thus:
// Open recordset for sites' pages
$result
= mysql_query("SELECT * FROM pages ORDER BY `published`, `urlpage` ASC", $link);
$total_rows = mysql_num_rows($result);
Remember that updating (and replacing the /admin/index.php file) will require you to re-apply this modification. But perhaps it is an interesting idea to make this configurable.
Cheers!
Xander.
