I'm looking for modules that will enhance management of block visibility.

At the moment the new need *seems* to be to control block visibility concurrently with node (page) editing.

I spotted http://drupal.org/project/block_node_visibility http://drupal.org/project/bpv http://drupal.org/project/block_assign

But none seems to match our needs.

A longer list of modules that I may have missed or a different point of view on the problem may put me on the right track.

Surely having a LONG list of blocks on the node edit form doesn't seem a good idea.
