There is also another project (vitaminC I think) for new look in admin part of xoops.
<form style="margin-top: 0px; margin-bottom: 0px" action="<{$xoops_url}>/user.php" method="post">
<input name="uname" type="text" value="" size="14" />
<input name="pass" type="password" value="" size="12" />
<input name="op" type="hidden" value="login" />
<input name="submit" type="submit" value="<{$smarty.const._LOGIN}>" />
</form>
<{foreach item=block from=$xoops_ccblocks}>
...
<{/foreach}>
