I would like to be able to use a region which is to contain the title of the current node. In the default theme the title is output in the main content, but I want it in this custom region instead. But I cannot find a block for the node title. Can I create it?
Remove the title from the node.tpl.php and create a new block with the following PHP code:
<?php $node = node_load(arg(1)); print $node->title; ?>
Enable visibility only on view node pages.
CCK Blocks is a very handy module for these things, but unfortunately the node title isn't listed as an element in display mode.
If you are on D7 and you are using Omega theme, Delta module should work for you. Check specifically Delta Blocks module from that package.
