administer blocks

I'd like a module that would allow administrators to more intuitively determine block placement, both on the page and throughout the site, using the core Drupal block system. This is what I'm thinking of:

      o A button on every page should allow administrators to edit the blocks <i>for that page</i>.
      o When not administering blocks,
            + Quick links (ajax) should be displayed on each block for
                  # hiding from this page
                  # hiding from all pages with path …
                  # configuring the block

Det känns som jag har fått hjärnsläpp som inte kan lösa detta till synes enkla problem i Views 3: Jag försöker flytta Views-blocket "Main page content" till den inaktiva regionen under Admin -> Structure -> Blocks men får felmeddelandet Region for Main page content block field is required.. Jag har i stället ett antal egna block från Views som ersätter detta block i Content-regionen i temat.

Fräsch Drupal 7-installation, med senaste versionen av CTools och Views 3. Allt ser bra ut i Admin -> Reports -> Status.

Vad göra?

I have a top domain and 4 subdomains running off the same code in my Multisite setup. I'm running 6.19 Drupal core that I upgraded last weekend.

In two of these subdomains, when I go into Administer/Blocks, I get a white screen and this message:

Fatal error: Cannot redeclare block_admin_display() (previously declared in /--mysite--/modules/comment/block/block.admin.inc:12) in /--mysite--/modules/block/block.admin.inc on line 23

It is strange because the top domain and the 2 other subdomains go into Blocks OK. If it's not a Multisite problem, is a Drupal code problem?

I'm in the middle of trying to figure out the right experience for installing and using Acquia's hosted search platform. In doing so, I had to think about how to build pages that were Solr enabled. In parallel, I've been thinking about a better way work with blocks. The two topics were fairly connected, so I started working on some concepts.
