The default position for the menu in WordPress 2.7 is on the left, but since the scroll-bar is on the right, some people wanted the menu over there too. Plus a lot of blogs/websites have menus on the right so menu on the right seems to be a pretty popular option.
This plug-in moves WordPress admin menu to the right side of the screen.

By default wordpress menu system, wordpress can only automatically add/remove top-level page to/from menus
<ul>
<li>When publish top-level page then add it into menus</li>
<li>When move top-level page to trash then remove it from menus</li>
<li>When restore top-level page then add it into menus</li>
</ul>
this feature has no effect with subpage (child page), but Auto Subpage Menu can
<ul>
<li>When publish subpage (child page) then add it into menus (if its page parent exists in menu)</li>
<li>When update subpage (child page) then update menus</li>
<li>When move subpage (child page) to trash then remove it from menus</li>
<li>When restore subpage (child page) then add it into menus</li>
</ul>

Auto Subpage Menu

The idea is good but the support is not very good. So if you find another plug-in with similar functionality I would advise to try that!
